The movie sees her work once again with Seth MacFarlane as he makes feature film directorial debut and actor Mark Wahlberg.
The actress enrolled into acting classes at the age of nine and it wasn't long before she landed her first TV role.
She made her television debut back in 1994 when she took on the role of Hope Williams in Days of our Live before going on to 7th Heaven and Gia.
Her breakthrough TV role came four years later when she joined That 70s Show - where she lied about her age to land the part.
And the TV success continued as she joined Family Guy in 1999 as she replaced Lacey Chabert to voice Meg Griffin - a role that she continues to voice.
During the noughties she continued the TV work as well as appearing in movies such as Get Over it and American Psycho 2 but it was to be 2008 that was to be her major breakthrough year.
That year the actress starred in Forgetting Sarah Marshall with Jason Segel and Kristen Bell and since then she has not looked back.
She showed off her comic ability with that movie and she went on to be nominated for a Teen Choice Award.
She followed that up with Max Payne and Extract before she teamed up with Denzel Washington in The Book of Eli.
It wasn't long before she returned to comedy with Date Night, a movie that was a hit at the box office.
But she showed a completely different side to herself in with her next project as she teamed up with Natalie Portman for Black Swan.
The movie was directed by Darren Aronofsky and it was the most serious project that the actress had undertaken as she played a rival ballet dancer to Portman.
It was a great performance from the actress and the movie went on to be nominated for five Oscars - including Best Picture.
Last year she enjoyed success with Friends With Benefits but this week she is back with her new comedy Ted.
Ted tells the story of John Bennett (Wahlberg), a grown man who must deal with the cherished teddy bear who came to life as the result of a childhood wish...and has refused to leave his side ever since.
And we are going to be seeing plenty of the actress as she has already completed work on Tar and Hell & Back.
Early 2013 will see her star in Oz: The Great and Powerful, joining an all star cast that includes James Franco, Michelle Williams and Rachel Weisz.
She will also be starring in Blood Ties next year which is the latest movie from director Guillaume Canet.
Ted is out now.
