Jennifer Aniston shares a blissful relationship with Justin Theroux as they are being rumored of tying knot or expecting to have a baby.

In an interview promoting her new project "Five," Aniston cleared the rumors about her engagement to a bad habit -cigarette smoking - could possibly be the reason behind those pregnancy rumors. Jennifer also cleared that while having Justin by her side, there are no plans for marriage yet as she was focused on promoting Five for the past month.

Furthermore, Aniston made clear that there are no engagement or wedding bells happening soon. She said that she was already married once and that she no plans of getting married at the moment. Thus, she also doesn't know if she will be marrying again.

They are just happily enjoying their lifestyle as they split their time living in Los Angeles and New York City. As to her weight gain, Aniston said she is not pregnant. It is only her saying goodbye to smoking that made her gain a couple of pounds. She actually pledged to stop smoking in 2002, but was still seen to be lighting up a cigar last year.

At least, Aniston can stay strong as she can find inspiration from other celebrities who also quitted the habit. A few stars such as Matt Damon, Ben Affleck, David Arquette, Courteney Cox, ex-husband Brad Pitt, Mel Gibson and Ashton Kutcher.

These stars have been known to engage into certain activities such as therapies and other self-help practices that made them stop smoking. For some, their kids and families are there most important reasons why they had to quit.
