Jennifer Aniston certainly knows how to promote a movie. In recent weeks, the actress has set tongues wagging with a new man and a new tattoo.

And having alluded to her 'very happy' personal life with Justin Theroux in an interview on GMA this morning, the 42-year-old actress wasted no time in keeping herself in the spotlight - by stepping on in a very sexy LBD.

Jen put her incredible legs on show in the lacy number as she arrived to tape an interview on the The Daily Show with Jon Stewart.

Earlier in the day the former Friends star played it casual in jeans as she made her way between interviews in the Big Apple promoting her new movie Horrible Bosses, ahead of the U.S. premiere on Thursday.

Talking on today's Good Morning America, Jennifer alluded to her new body art, a tattoo of her dog Norman's name who passed away recently, saying: 'I wouldn't say I'm squeaky clean in any way.'

She also spoke on the show of her new relationship with 39-year-old actor Theroux for the first time - though she declined to actually name her beau.

Appearing on the breakfast show to plug Horrible Bosses, in which she plays a kinky dentist, she said she was 'very happy' in her personal life, and added: 'I'm extremely lucky and extremely happy.'

Before passing away at the age of 15, Jen's dog Norman had regularly accompanied Aniston to film studios and her former Friends set.

She had said in the past: ‘Norman goes with me on location – I’ve got to take Norman. He’s my baby boy.’

And the pair were pictured together on many occasions, from going for walks on the beach, attending photo shoots together and going on holiday.

Aniston confirmed that the tattoo was a tribute to her pooch while talking to James Lipton during a taping of Inside the Actors Studio, People reported.

The star's first inking has also sparked speculation that she might have been influenced to get the etching by her new edgy boyfriend Justin - who is heavily tattooed.
