Pop Tarts: Paris Planning Pregnancy; Christina Aguilera Poses Nude

Post-pokey Paris Hilton is undoubtedly looking better these days, having shed her extensions and sporting panties as she parties.

Now, the heiress-turned-music-maker is ready to enter the next phase of her not-so "Simple Life" and have a baby — at least within the next two years.

"Seeing Nicole [Richie] just makes me want to be a mom," she told Pop Tarts at Tuesday night's "Share the Passion" party celebrating the one-year anniversary of Nissan Live Sets on Yahoo! Music.

"I’m like, 'Oh, my God, I need a baby now' because I want our kids to be able to play together like we did when we were 2 years old, so not yet but hopefully in the next two years."

Hilton also said that Richie's pregnancy has caused the on-and-off best friends to trot down memory lane.

"I’m so happy. Nicole and I had lunch yesterday and we were looking through all our pictures," Hilton said. "We’re both so excited, and she’s so happy and she looks so beautiful. I just can’t wait to see the baby."

It takes two to make a baby, however, and Hilton is enlisting a little help from the North Pole in her search for a man to do the "Simple" deed.

"On my Christmas wish list this year is just to be with my family and just be happy and find a nice boyfriend," she said.

But Hilton's future mini-mogul had better be ready to hear his/her mama make music and take on the world.

"I just did my Asia tour. I went to Korea and China and Tokyo in the past two weeks. It’s incredible — I’ve never been there before and it was a lot of fun just being out there and doing a lot of business, and I’m going to go back again next year and hopefully a lot more in the future, too," Hilton told us.

"And I just finished a movie called 'Repo! The Genetic Opera!' and I have 12 songs in it, plus I’m working on a new album. Very busy."

So busy, in fact, that the perennial partier didn’t have time to appropriately color coordinate on Monday. Paris was popped prancing through Los Angeles in a sexy blue dress and stockings … but we’re not too sure about those pink panties beneath.

And lucky for the heiress, she won’t have to run for cover if she so happens to run into Christina Aguilera after "accidentally" announcing her pregnancy during the VMAs.

"Because I hadn't said anything, people thought I was trying to keep it this big, bad secret, and that's not the case at all," the "Dirrty" dame told Marie Claire magazine. "I just wasn't commenting. I'm not being like, 'Hey, everybody, I'm pregnant!' I'm not that girl."

And now that the secret is out, Ms. Xtina is joining the ranks of Demi Moore and Britney Spears in posing nude while pregnant.

"If you're too sexual, you're slutty. If you're not sexual enough, you're a prude. I have more than one side of me that likes to get out on a stage and sing," she added. "Sometimes I want to be aggressive; sometimes I want to feel empowered in my sexuality and my vulnerability. I want to put all that out there."

Inspired by Britney?

It’s no secret that some stars think they’re above the law, and it seems Steve-O (aka Jackass) slips swiftly into that category that once was reserved for Spears.

Pop Tarts popped the screen star roaming the red carpet at the Gene Simmons Roast in West Hollywood on Monday night, proudly puffing on more than nicotine.

The daredevil also pulled down his pants while posing and pretended to light his privates alongside the illicit bong in his other hand.

However, Steve-O clearly wasn’t there to support the "Kiss" man being roasted.

"I’m not a fan of Gene Simmons; I’m not here to see him. Where’s Britney? Is she coming?" he said before disappearing to his next adventure.

Hmm … and it turns out the music/merchandise mogul himself certainly wasn’t there to see Steve-O, either.

"I don’t care about celebrities or anyone really except myself and my family," Simmons said. "And making money, that’s the most important thing, because you need to make money in order to get women to make music … if you know what I mean."

Speaking of Spears ... the pop princess wanted to trade baby days with Kevin Federline so she could shoot her new music video, but Fed-Ex refused, forcing Spears to shoot overnight instead, TMZ reported.

And it seems Spears is playing tricks on her "pals" the paparazzi. Brit and her back-up dancers are all donning identical blonde wigs, shades and trench coats for the pop tart’s new music video … can you spot the real Spears?

Cate's 'Not There': Blanchett Embraces Being a Boy

It’s not easy morphing into a male, especially when you are a "Babel" beauty, but ironically it's Cate Blanchett’s fine-boned features and porcelain pout that paved the way for her to forgo her femininity and become a boy in the new Bob Dylan flick "I’m Not There."

"The film is a composite and that has been the biggest challenge for me," Blanchett said of her role as a folk musician going electric. "It's almost like each of us [is] inhabiting a different part of the outward persona, imagining what the inward persona of Dylan might possibly be."

The lyrical legend himself is about the only thing "Not There" in the early Oscar-murmured movie — six stars take on the role of Dylan in the film.

And much like his own private life, which he tries to keep from the media, co-star Heath Ledger wants to keep us "Blowin’ in the Wind" wondering about what was really happening in Dylan’s brain.

"It’s not a conventional biopic — it’s not a movie that’s trying to put Bob Dylan in a box and categorize him; it's not a documentary, obviously, it's a highly respectful visual portrait of a man that preserves his mystique," Ledger said. "And I think that's the biggest gift of the film is it's not defaming him in any way — it's not presuming to know too much about him."

But it seems as though "The Times They Are A-Changin’" in terms of Ledger’s love life. He’s been busted bumming about with Kate Hudson since his split with Michelle Williams earlier this year, and although the pair have denied they’re dating, an insider has told us that Heath is opening his heart again.

"A break-up is hard enough, but when you’ve got the pressures of the press, the pain is even more intense," our source said. "But Heath is finally ready to move on — he’s focusing a lot on his career and being a dad, of course, but he is someone who needs companionship and he’s ready to find that special somebody again."
