Vanessa Hudgens of High School Musical "fame" better keep an eye on her man…or better yet, an all-over body condom…as Paris Hilton has apparently set her sights on the teen heartthrob. 24/Sizzler reports:

In the new issue of OK!, out today, Paris Hilton tells the magazine of Zac, “I think he’s beautiful. He’s young but gorgeous. I saw him on the cover of Rolling Stone, and he looked really cute.”

What’s weird is how many guys fall under her spell. Isn’t anyone afraid of herpes anymore? In an even more frightening report from E! Online (regarding an interview with the U.K. edition of Elle), apparently Paris wants to reproduce. Now that’s hot.

On what people think about her
“I wanna have like a family and a guy. Y’know, it just upsets me because I’m not anything like what people say about me, and this cartoon character that they’ve made of me is just completely false. It makes me mad that I’m such a good person and I’m treated like that by some people, I just don’t get it.”

On how she’s prepping for pregnancy
“I just started working out and it feels great. It gives me so much energy. I want kids next year, so I’ve got to get my body ready.”

Is there some sort of Paris Hilton checklist or something? Who just up and puts kids on their calendar? Well, Paris Hilton does. I’m guessing her checklist looks something like this:

-Get famous for absolutely nothing

-Bone everyone in Hollywood.

-Create sex tape.

-Find cure for herpes, cuz that’s not hot.

-Get DUI

-Go to jail.

-Go on Larry King and discuss finding God. That’s hot.

-Have kids-dress them in really cool outfits. Keep them with dogs.

-Hire team of nannies to take care of kids.

Hey, in her defense, she’s accomplished a lot of her goals.

While John Mayer is busy going green, Us Magazine is reporting that his ex, Jessica Simpson, is busy being green…with envy.

A source close to the singer tells Us Simpson is “really jealous” that ex John Mayer is seeing Cameron Diaz. “She had her mouth open a mile wide when she found out,” says the source. “She just freaked.”

And the way they could tell this was her mouth being open a mile wide? Have they seen Jessica Simpson before? Her mouth could fit a freight train twice on Tuesday and she shows us that in every photo she takes.

Simpson, 27, parted ways with Mayer, 29, in May after dating him on and off for seven months, and “she thinks about him all the time,” says the source. “She is so not over him.”

Meanwhile, Simpson seems to be a distant memory for Mayer, who has continued his summer romance with Diaz, 35, in NYC. Though they spent August 22 and 23 apart (he hit the gym and recorded at a studio; she shopped and then lunched at Mary’s Fish Camp), they finally squeezed in quality time in the wee hours of August 24 at hot spot Socialista. The pair — who left at 4 a.m. through different exits — “were very cozy,” says a witness.

But what, pray tell, of the rumored romance between Cameron and Bradley Cooper? E! reports:

Sources close to Bradley and Cameron Diaz tell me that the two have been dating the past couple weeks. Pretty adorable, no?

Bradley’s rep insists that it is "not true" that the two are dating. However, insiders tell me that Cameron and Bradley have been busy sending flirty text messages to each other throughout the day and spending quite a bit of time together.

I can only guess that Cameron must be good in the sack cuz that face could be most people’s butt double.
