Kristin Cavallari showed off her million dollar smile as she filmed scenes for the George Lopez’s late night show in Hollywood on Friday afternoon (November 20).

While shooting the upcoming comedy skit outside of the Catherine Malandrino store, The Hills star could be seen spilling her cup of coffee while talking on her cell phone.

Nobody said talking and drinking at the same time was an easy thing to do!

Meanwhile, Kristin’s co-star is opening up about her unstable relationship with the controversial reality TV starlet.

At a recent US Weekly event, Stephanie Pratt told MTV: “I heard a rumor that Kristin Cavallari was being honored with a Hot Hollywood Award, so yeah, I got to support a castmember. I think it’s fab. I’m living by ‘grateful and not hateful.’ I love everyone. I’m just trying to be happy for everyone. So congratulations to Kristin. [She] so deserves it.”

She adds, “She was reality TV’s biggest star when she was 17, and then she disappeared. Then she came back with a vengeance, and she’s everywhere. And I think that really deserves the Comeback of the Year award, so well deserved.”

Between takes, the fiery red 21-year-old actress took to her iPhone to snap a few pics of the nearby paparazzi before resuming production until sunset.

As for what we can expect between the Gia-Adrianna storyline? “There’s been a real void in the 90210 universe in terms of gay and bisexual characters, so it was always my intention to find the right way to tell a modern story about being a non-straight — or non-entirely straight — teenager,” showrunner Rebecca Sinclair tells EW. “It’s crazy that we don’t have any stories about that.”

As for how this same-sex fling differs every other gay romance on TV? “This isn’t a fling,” she adds. “We’re coming at this [relationship] from a genuine place and not going, ‘Let’s do a titillating story that will grab some promotion.’ This is a real aspect of teenager life that’s interesting.”

Dressed in a green picnic tablecloth, Kourtney Kardashian was spotted out and about in Los Angeles today (November 20).

After doing some shopping at CVS for toilet paper, toothbrushes, and cotton squares, the mum-to-be then proceeded to Starbucks where she treated herself to coffee and raisin bread!

Meanwhile, Kourtney’s baby daddy is opening up about his girlfriend’s pregnancy.

Scott Disick, the on-and-off boyfriend of the Keeping Up with the Kardashians starlet, has spoken up about the forthcoming addition to their family.

While the 30-year-old reality TV star is weeks away from giving birth, Scott chose to break his silence and open up about the “blessing” they have.

He tells Life & Style, “The pregnancy was a blessing. It’s our time to be together and start sharing a new life.”

When asked how the whole thing has changed him, he replied that while he was a “bit young” when they met, he now knows he has grown as a person.

“I’m much more productive with my time and my life. Kourtney’s family knows I’ve changed. They know I treat her well and that I’m here for her in every way. Now the trust is all there.”

Although he says they will be together forever, a marriage “isn’t the biggest deal” in their lives right now.

Scott and Kourtney are expecting their baby boy on Christmas.

After spending all week in London promoting her latest album, a moody Rihanna was seen arriving at LAX Airpot in Los Angeles today (November 20) following an exhuastive day-long flight.

The Russian Roulette singer is back in L.A. just in time to meet with her stylist and prepare for Sunday night’s American Music Awards.

Meanwhile, Rihanna has shot down reports she is dating 90210 actor Tristan Wilds.

“This is funny: I had a house party, and you know how you hold house parties and people come over you don’t even know,” she says. “He came by, brought his friends, and everyone was hanging out, but I don’t even have his number. So I don’t know how I could be dating him.”

Like her ex-boyfriend Chris Brown, Rihanna says she is not ready for another relationship. “I don’t think I have all the time for a commitment right now, or the energy. A relationship is another life, another career, really.”

Jessica Simpson stepped out in Beverly Hills today (November 20) for lunch — but instead the blonde beauty was given an ample serving of paparazzi attention.

Joined by her entourate — including friend Kacee Cobb, hairstylst Ken Paves and her strangely dressed father Joe Simpson – Jessica was welcomed by a barrage of shutterbugs as she made her way inside Sur restaurant after getting her hair did at Ken’s salon.

Happy birthday, Bronx!

Who is tuning into Sunday night’s American Music Awards?

All eyes will be on Jennifer Lopez, shown in rehearsal here yesterday at the Nokia Theater in Los Angeles. The 40-year-old diva will be singing her first new single Louboutins – from her upcoming new album called Love? - and she’ll be wearing a pair of red-soled heels designed just for the performance by Christian Louboutin.

You can listen to the dreadful new song HERE.

Look for fireworks and an on-stage costume change as part of her act, too. “I think it’s going to be good,” she says.

Janet Jackson is scheduled to open the show with an 8-minute presentation. Others slated to perform are Keith Urban, Carrie Underwood, Daughtry, Kelly Clarkson, Adam Lambert, Jay-Z, Shakira, Lady Gaga, Eminem and Alicia Keys.

Rihanna likes her men the way we like our burgers — big, thick and juicy!

The Russian Roulette singer says size is at the top of her priority list when it comes to finding the perfect partner.

“He has to be good in bed and the size matters,” she tells German mag Bravo when asked what a guy needed to impress her. “The inner beauty counts as well, but without a toy it doesn’t make it fun. Right now I don’t want to have a serious relationship, I want to have fun. I love flirting at the moment. I’m single and I’m enjoying my freedom. But I don’t give my phone number out that often. But if I’m dating, I check the boy from the top to the bottom.”

Famous for once dating celebrity felon Chris Brown, 21-year-old Rihanna was most recently linked to 90210 actor Tristan Wilds.

As expected, the Victoria’s Secret fashion show last night was filled with beautiful girls and lots of skin — but what came as a surprise was a takedown of the press’ treatment of Megan Fox by none other than Transformers director, Michael Bay.

As you may recall, Megan famously referred to him as a “nightmare,” and “Hitler” in recent interview.

So, what are his thoughts? “I love her,” he tells USA Today. “It’s just, she’s young. Everyone’s got to give her a break, she only…23? It’s just hard. I’ve traveled around the world with her and she’s just like this world symbol now, you know?”

So are her diatribes something that shouldn’t be taken seriously? “Absolutely,” he said. “She called me (after the Hitler comment) and goes, ‘It’s all bullsh—t, Mike.’ The press, they just like to prey, and stalk, and pounce and find a good little juicy thing. But she’s always wanted to do these crazy comments. That’s just her. She’s great.”

He also said, “She’s got a great part in Transformers 3,” and he said he’s currently working on the script. So Bay’s not planning on getting revenge by, say, killing her off? “No, no. no,” he said, dismissing it. “She gets enough of that already.”
