Jennifer Aniston's acceptance speech during the 2012 MTV Movie Awards (where she received the Best On-Screen Dirtbag award) has come under the scanner, with reports of the Hollywood star being drunk now circulating the Internet.

The former Friends star's speech was reportedly slurred at several points and the 43 year old actress was reported as being shaky on her feet during the ceremony.

"I mean, do you know how long I have tried to have somebody let me unleash my onscreen dirtbag? And thank god this category just popped up... so I would like to say thank you to the television show Friends for letting me unleash the inner sweetheart. And here's to [Horrible Bosses director] Seth Gordon for allowing me to be a dirtbag. Thanks, dirtbag," Aniston said at the 2012 MTV Movie Awards.

There are other rumours concerning the Horrible Bosses star as well, this time concerning a break-up with boyfriend Justin Theroux. Apparently Theroux is beginning to feel the pressure of Aniston's star life in Los Angeles.

"He's crowded out by Jen and her life in LA. He misses his buddies and the intellectual scene in New York. Justin loves her, but she's making him crazy because she won't leave his side. They rarely spend a night apart. It's a little odd to blame their rows on houses, but they were arguing like crazy in the smaller place. Jen is a bit of a neat freak and likes her space. She wasn't used to living with someone full time - especially somewhere so confined. Jen loves Justin but worries that the first flush of excitement may have gone, so she arranged for some low-key counselling sessions," Now magazine reported.

However, it may not be as bad as all that since the Daily Mail reported the couple at the Chateau Marmont Hotel in West Hollywood with their arms around each other. The couple had earlier announced their wedding, to be held sometime later this year.
