Jennifer Aniston wants to be a serious actress

Jennifer Aniston wants to be recognised as a ''serious actress''.

The 'Cake' star is reportedly desperate to be nominated for an Oscar for her role in the movie at the upcoming awards ceremony in Los Angeles in February and no longer wants to be seen as 'America's Sweetheart.'

A source close to the 45-year-old beauty, who is engaged to 'The Leftovers' star Justin Theroux, said: ''Winning an Oscar has been a dream of Jen's, and she knew 'Cake' could finally be her ticket.''

The former 'Friends' star - who has been nominated for Screen Actors Guild and Golden Globe awards for her role in the movie - has revamped her wardrobe as awards season approaches.

The insider said: ''Jen is buzzing. Even a nomination would be rewarding for her on so many levels!

''She's truly on the campaign trail now, which is why she's been buttoning up, choosing demure outfits and even wearing glasses.''

The actress underwent a make-under to help her embody the role of Claire Simmons, a woman who suffers a car crash that leaves her with scars all over her body, in the film, AND hopes it will help her take her career in a new direction.

The source told America's OK! magazine: ''Jen was initially nervous about looking so raw on camera. But after really digging into the character, she had a lot of fun.''
