From the red carpet of a movie premiere to the after party of a film, lovebirds Jennifer Aniston and Justin Theroux are painting the town red with their heavy PDA. And you thought that the stunning couple was calling it quits? Not anytime soon, we bet.

The couple made a stellar comeback on the red carpet at the recently held premiere of Theroux's latest HBO series, “The Leftovers” on Monday. Not just that, the lovey-dovey couple were caught attending the afterparty for the upcoming flick Tao Downtown post their red-carpet appearance.

An eyewitness says that "Justin and Jennifer were very lovey dovey. They were upstairs in a private VIP area all night with Liv Tyler and Jason Bateman."

The source says that the duo acted like "they were at their own private party," adding that "they didn't socialize much with other people" and "stayed upstairs."

"Jen and Justin were very intimately talking for what seemed to be a long time," the eyewitness reveals. "They looked very happy together."

Jen and Justin walked the carpet hand-in-hand as well as cuddled for the camera, holding each other tight around the waist.

The happy photos are a confirmation of the couple's blissful relationship. The longtime pair are working out well, despite their crazy schedules and careers.

And yes, as for the age-old rumor that Aniston is pregnant, know that there's no truth to the baby buzz.
