Zac Efron has picked up a lot more grown up female fans recently as he steps out from his Disney teen heartthrob persona and into Hollywood’s latest leading man.

The Lucky One clearly has a one track mind of late – most noticeably when he accidentally dropped a condom from his pocket at a recent red carpet event and was pictured rummaging around in his pants Down Under.

Jennifer Lopez has a new younger man on her arm, and a new younger look to match!

The recently separated singer, 42, showed off fuller, plumper lips in New York City on Tuesday – all the better for kissing new love, 24-year-old Casper Smart! - and prompting speculation that she has gotten cosmetic surgery.

“Has J. Lo become an Idol for plastic surgery?” asked celebrity surgeon Dr. Anthony Youn, who has not treated the star.

Meet Kristina Rei.

The 22-year-old St. Petersburg, Russia nail technician has spent more than $6,000 on 100 silicone injections to her lips, in hopes of resembling her favorite film heroine, Jessica Rabbit.

"I think I look fantastic and it makes me happy," Rei said. "Sometimes strangers shout names at me in the street -- like big lips -- but I don't care. I want to go more extreme. I want to look like a cartoon character.

Angelina Jolie is that you?

Sandra Bullock was showing off her luscious lips Tuesday, prompting speculation that she may have gone under the knife (or syringe) to achieve a decidedly plumper pout, and RadarOnline.com has the photos.

Lindsay Lohan isn't just giving lip service to living a healthier life in 2011 -- as photographers snapped the Mean Girls star, 24, hitting the gym in West Hollywood on Wednesday.

But, we couldn't help but notice Lindsay's plumped-up pucker -- especially since her form-fitting blue t-shirt read: 'True Beauty Is Within'.

Apparently, sometimes, true beauty can also be found on the outside.
