Jennifer Aniston doesn't care at Brad Pitt's engagement to Angelina Jolie, a friend of the actress told E!Online.

"She doesn't care," a pal of Aniston told E!Online. "She really doesn't. She's happy with Justin. She'll probably marry him. She's moved on. People don't want to believe it, but she has."

Pitt was married for five years to Aniston until they divorced in 2005 amid rumors that Pitt fell for Jolie while filming "Mr. & Mrs. Smith."

In an interview in 2008, Aniston told Vogue magazine that Jolie was "inappropriate" and "uncool" discussing details on how she fell in love with Pitt on the set of the movie, because at the time she was unaware that it was happening.

Their separation sparked media frenzy until today.

Currently Aniston is dating actor Justin Theroux.
