She's riding high on personal and professional success, and Jennifer Aniston was beaming with confidence as she arrived at the 81st Annual Academy Awards tonight (February 22).

The "He's Just Not That Into You" hottie made her way down the red carpet with her boyfriend John Mayer, looking like the picture of romantic bliss.

Jen sported a strapless champagne-colored beaded gown along with a braided-bangs hairdo while Mayer looked dapper in a classic black tuxedo.

Once inside, Miss Aniston joined funnyman Jack Black onstage, looking elegant as she presented one of the night's awards.
