Zac Efron and Vanessa Hudgens are pretty coy about their personal relationship in the public eye, but the Disney duo went all-out in "High School Musical 3" — and seeing their onscreen chemistry gave co-star Ashley Tisdale a heart-warming buzz.

"I'm a total romantic, I loved watching romantic comedies growing up like 'My Best Friend's Wedding' and so obviously, like, I just love watching Zac and Vanessa because it is such a sweet and romantic relationship so of course you're like, 'aww' whenever they kiss and everything," Tisdale gushed to Tarts. "But just watching them on set is really awesome, it's beautiful."

But sadly, Efron says he isn’t as sweet as his character Troy Bolton in real life — although he did have some tips for the young men out there.

"I can't say that I've ever did anything quite so Romeo and Juliet," Zac admitted. "But it's the small things. Guys remember, it's the small things you do."

Glam to Goth: Jessica Alba a Night Owl in NYC

Jessica Alba is certainly making the most of the Big Apple social scene, and was spotted going gothic at the "Seven Deadly Sins" bash at New York's STK last Wednesday night.

Pop Tarts spotted the 27-year-old actress, hubby Cash Warren and her "Sin City" co-star Jaime King sneaking into the swanky restaurant without baby Honor Marie in sight.

Both Cash and Jess were doused in black from head-to-toe and even though she has well and truly got her pre-baby body back, Alba apparently didn't deprive herself of the fine wine, truffles and pudding. (Mind you, we're told she also got stuck into some strong cocktails at Heidi Klum’s Halloween party two nights later before boogieing over to the Beatrice Inn in the early hours).

Warren and Alba also enjoyed yet another night of partying (in lieu of parenting) in the city that never sleeps at the recent premiere of Madonna's directorial debut "Filth and Wisdom." The Hollywood hotties even hit up the star-studded afterparty on Orchard Street. Thank goodness for nannies, right?!

Despite telling Tarts (while she was preggers) that she didn't want to commit to any projects for quite a while to instead focus on playing mom, Alba just can't call her own "cut." The in-demand actress has been busy filming on the Staten Island set of the drama "An Invisible Sign of My Own" but told insiders that she plans to bring her 3-month-old daughter to the location on most work days.

Eva Longoria Definitely Not Expecting ...

After months of denying pregnancy rumors — but fueling the speculation by staying well away from raw food, alcohol and cigarettes — Eva Longoria has proven once and for all that she really does not have a bun-in-the-oven, well at least that's what we hope.

Pop Tarts spies spotted the "Desperate Housewife" puffing away with pals at last week's Los Angeles launch of the new BlackBerry Bold by AT&T (not to mention looking like her old svelte self again).

Sans hubby Tony Parker, Longoria attended the lavish affair on the arm of TV personality Mario Lopez who narrowly avoided an awkward run-in with his "Dancing With the Stars" partner and former flame, Karina Smirnoff.

Smirnoff apparently had a "mini freak-out" and ran inside as soon as she spotted her ex enter the carpet. The two went thru a messy split a few months ago after reports surfaced with regards to Lopez's wandering ways.

Other stars spotted (scooping up a free BlackBerry Bold) at the bash included Adam Levine, Adrian Grenier, Cuba Gooding Jr., Dustin Hoffman, Hayden Panettiere, Kate Bosworth, Katharine McPhee and Molly Sims.

Hearst Halloween: Lydia is (Literally) a Liar

Last week Page Six columnist Richard Johnson slammed Lydia Hearst for going back on her word under the damning headline "Lyin' Lydia." The model/socialite recently quit her position as a special guest columnist for the New York Post after accusing her editors of fabricating disses against her family business, Hearst Publications.

But Lyds still swore she wrote all her own material — yet according to Johnson, she was only ever "interviewed by a reporter, who put her thoughts into cohesive paragraphs."

But while most celebs would issue a "no comment", Miss Hearst was obviously more than happy to have a laugh at her own expense. The 24-year-old turned up to host her Halloween bash at 1OAK last week dressed as a sexy reporter in black bikini and top hat with a "Page Six Six Six" midriff. She even carried a copy of the very paper that so publicly pounded her that same day.

So what exactly was Hearst's costume?

"I’m Lyin’ Lydia of course," she responded, but told pals that her version of the story remains unchanged and that she never would have talked down on the Hearst brand as the Post claimed.
