Jennifer Aniston admits to working hard to look as good as she does. An avid fan of yoga and running, the actress has been looking better than ever since she began filming Marley & Me in Miami. Whether she’s in a teeny white bikini on the beach, or simple jeans and a t-shirt, the 39-year old star seems to have transformed herself into a Greek goddess.

But is her stunning new appearance a result of her work, or has she had work done?

The former Friends star has publicly admitted to having surgery on her nose. "I had a [deviated septum] fixed," she said, calling it the "best thing I ever did."

But according to NYC-based plastic surgeon Dr. Kevin Tehrani, who has not treated the actress, Jen may have had cosmetic nose surgery as well. "Her tip appears to have been corrected; it looks very defined now," Dr. Tehrani tells OK!. "I think the bridge of her nose looks narrower as well. It’s very common for people to say they’re correcting a deviated septum when they are, in fact, getting cosmetic nose surgery."

But according to Jen, the nose is as far as it goes — she has always denied having any cosmetic surgery, and she’s downright adamant that she’s completely natural. "As boring as it sounds, it’s still all mine," she said last year.

Dr. Tehrani respectfully disagrees. "It looks like she may have had some filler in her upper lip. It’s subtle, but it benefits her face," he says. "Her brows look elevated, which means she may have had some Botox in her forehead." Both procedures are so easy and painless that, according to Dr. Tehrani, Jen could have done them on her lunch break!
