Vanessa Williams’ son Devin is gearing up for his first job now that he’s getting ready for his first car.

The mother-son team recently signed Allstate Insurance’s Home For The Holidays teen safe driving contract.

Vanessa, 45, is a single mom to Melanie, 21, Jillian, 19, Devin, 15, and Sasha, 8.

What’s the best thing about having children? “It’s never-ending unconditional love,” the Ugly Betty star tells me.

But just because she’s on a hit show doesn’t mean her kids are on easy street.

“The past two girls, as soon as they got jobs, they got used cars,” Vanessa says. “No one got a brand new car. We’ll see what kind of used car he gets.”

While Melanie worked in a boutique to pay for a “colorful, yellow, used” Volvo S40 and Jillian worked at a children’s day care to fund her ride, Devin may find his future in a shoe store.

“I want something that deals with fashion,” he says. “I’m really into sneakers, clothes and everything.”

And about the big rock he’s sporting in one ear? He got it for eighth-grade graduation.

“It’s faux,” Vanessa says. “It isn’t real, believe me.”

Julianne Hough doesn’t believe in worrying about weight during the holiday season.    

“I don’t diet,” the Dancing With The Stars beauty, 20, tells me. “I eat!”

Julianne will perform tunes from her Christmas album Sounds of the Season: The Julianne Hough Collection on TNT’s Christmas In Washington, which airs Wednesday at 8pm ET.

She has already won the heart of fellow country singer Chuck Wicks. He agrees: She loves to eat.

“When I first met her, we sat down and talked over five different desserts in Las Vegas at the ACM Awards,” Chuck, 29, tells me. “We realized we had so much in common – you could see the sincerity in what she says, and she’s so genuine. She’s so beautiful inside that the outside’s just a bonus.”

Julianne has equal praise for her man.

“We complement each other well, and we really understand each other’s careers and passions,” she tells me. “He’s an amazing guy.”

Tune in Wednesday to catch Julianne – and Darius Rucker – perform.

Katy Perry sniffs her armpits when she’s offered a membership to New York Health and Racquet Club during the H&M Artist Gift Lounge held Friday before Z100’s Jingle Ball in NYC.

The I Kissed A Girl singer says gift lounges are one of the best perks of being famous.

“You want to leave a Paul Newman legacy,” she tells me. “We get a lot of stuff, and we get to give it back. I know that my girlfriend backstage has a real cracked-out Blackberry, and I got a new Blackberry. She’s getting it.”

As members of Paramore shop around, Sean Paul tells me he can’t wait to use the SodaStream soda maker, Canon PowerShot digital camera and Blackberry Pearl Flip Smartphone in the recording studio.

I bump into Brody Jenner in the hallway before the Madison Square Garden concert featuring Kanye West, Rihanna, Chris Brown and Leona Lewis begins. He had a last-minute wardrobe switcheroo. “I had my Dickies on before I came here, and my manager told me to take them off and put my jeans on,” he says.

Ashley Tisdale enters the press room, sporting brunette locks instead of her trademark blonde. How does being a brunette compare to being a blonde?

“I’m naturally brunette, so I feel back to myself, I guess,” the High School Musical star tells me. “Being blonde, it was so much fun. I think blondes and brunettes have so much fun, but I feel like Sharpay really owns the blonde, so I kind of feel back to Ashley in a way, so it’s exciting.”

Ne-Yo plays it cool when asked what he thinks about the rumor that Rihanna is expecting with boyfriend Chris Brown.

“Really?!” he says. “That’s a new one on me. I just heard that. OK. If she is, congratulations, and if she isn’t  -- come on guys, cut it out.” (Psst. Eyewitness acccount: Her stomach is totally flat.)

David Archuleta giggles through American Idol questions, but when Hayley Williams of Paramore is asked to pose alone for a fashion shot, she declines. “I’m not very fashionable,” she shrugs, ducking off with the boys. (Hm, Demi Lovato would disagree.)

Veronicas singer Lisa Origliasso says they taught the Jonas Brothers “everything they know” when the boys opened for the girl group in 2006.
 
“I think people look at them like they’re good boys, and they are good boys, but they’re very rock-and-roll,” her twin Jessica Origliasso tells me.

Here is Lady GaGa, who looks like a Muppet in her long blonde hair and super-long eyelashes. “It’s not a persona,” she tells me. “This is who I really am -- in all my origami glory.”

Up next is Jesse McCartney, who plays coy when it comes to dating. “The microphone has been my girlfriend for the last year,” he says. “I haven’t really done much.”

Get this -- Brandy doesn’t want to leave the press room when she’s asked to move along. Her new Rodney Jerkins-produced single is called Right Here (Departed). “It’s about being there for the people that you love,” she says. “Everybody needs somebody, so I thought it was a great song to reintroduce me back to the world.”

John Leguizamo, Freddy Rodriguez and Debra Messing light up the silver screen in Nothing Like The Holidays, which is in theaters now.   

The Christmas flick centers on family drama – something we try to avoid at all costs in the Nome home. So, why is it taboo to break bad news during the holidays?

“It’s like talking politics,” John tells me. “You never talk politics at a dinner because you know it’s going to end up in a fight. At the holidays, you’ve got to try not to bring up issues because you know it’s going to be a war.”

The father of two, 44, who is married to wife Justine, hasn’t been so lucky. “One time they got me drunk and then they used me as a whipping post. They said ‘How dare I talk about things in public that are personal? Who am I? The arbiter of the family?’ I don’t blame them. I think they were right. If somebody else would’ve called the people by their names., I would’ve been upset too.”

John continues, “Every family, every holiday is a reason for families to get together and have issues. It just comes naturally. A few drinks, and all of a sudden things come back from the past to bite you.”

Freddy, 33, who has two children with wife Elise, has avoided trouble during this time of year.   

“I think it happens during the holidays because people are together, first of all,” he tells me. “During the year, people are so busy with their own lives and they finally get together for three or four days. And people drink. There’s just this element of ease during the holidays, and they all want to get what’s off their chest.”  

He adds, “I think we all have a certain degree of dysfunctionality within our families, but my family is pretty functional.”

Nothing Like The Holidays is in theaters now.
