Jennifer Aniston is undeniably smitten and in love with her boyfriend Justin Theroux. Rumors are spreading that the actress is determined to marry him before 2012 ends.

After her much publicized divorce with Brad Pitt, Aniston has been careful on who to date not to mention who to walk down the aisle with again. The "Wanderlust" actress reportedly gave Theroux an ultimatum to propose by the end of the year or their relationship will be over.

The couple has been inseparable since they made their relationship status public. Last week, the 43-year-old actress shared a public kiss with her boyfriend during the acceptance ceremony at the unveiling of the Hollywood's Walk of Fame.

Justin sat next to Jen's father as they proudly listened to her while she gave away her speech.

"'It feels very surreal to be honest. I was born here and it's sort of something you went and saw as a kid and got excited about just walking and seeing the names," Aniston said.

"To imagine that you're going to be there is really special. It's fun."

After her split from Pitt in 2005, she was in and out of relationships including Vince Vaughn and John Meyer. Now, the actress enjoys her romance with Theroux who also appears with her in the movie "Wanderlust."
