There’s no denying that Jennifer Aniston is looking better than ever in photographs taken on the set of her new movie Marley & Me.

However, we couldn’t help noticing that the former Friends star appears somewhat...well, different, in recent pics.

The 39-year-old actress has spoken publicly about having surgery on her nose for ‘medical reasons’.

"I had a [deviated septum] fixed," she has said, calling it the "best thing I ever did."

But NYC-based plastic surgeon Dr. Kevin Tehrani - who has not treated the actress - believes that Jen may have also gone under the knife for cosmetic reasons.

He tells OK!,  "Her tip appears to have been corrected; it looks very defined now."

"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."

And the nip/tucks aren’t confined to her nose, according to the good doctor.

"It looks like she may have had some filler in her upper lip. It's subtle, but it benefits her face," he adds.
