Jennifer Aniston Justin Theroux: Actor Making 'Friends' Star Fat? [VIDEO, PHOTOS]

Rumor has it that the Friends actress and her 42-year-old screenwriter beau, Theroux, are seeking to expedite their wedding plans in an effort to say "I Do," prior to exclaiming, "It's a boy" or "It's a girl!" Recently, People magazine caught up with Aniston, 45, who attributed any potential weight gain to her fiancé's "amazing" cooking talents.

"The last couple of years since meeting this man have made me gain a couple extra pounds," she admitted, "But it's all worth it." The two have reportedly been a couple since May 2011, and have been cohabitating in a $22 million Bel-Air neighborhood home since January 2012. A few months later, reports of their engagement surfaced, and they are now said to be planning their big day for sometime in the near future.

According to an OK! Insider, they will be married in an intimate wedding ceremony at their LA home, with no more than 100 guests present. "Jen would love to have it outdoors, in the garden, but she's not having a repeat of her wedding to Brad," told the source. Will her ex-hubby Brad Pitt even be on the guest list? Or, how about her Friends? Apparently, she and her former costars won't be getting together anytime soon, as they seem "too busy to move forward with plans for a reunion special," at this time.
