Angelina Jolie 'Had Post-Pregnancy Tummy Tuck'

Angelina Jolie had a secret tummy tuck after the birth of twins Knox and Vivienne, according to reports.

The Tomb Raider star welcomed the babies -- her fifth sixth children with partner Brad Pitt -- in July.

And Jolie, 33, was so determined to get back her svelte figure, she decided going under the knife was the best option.

A source tells Star magazine, "She doesn't like to talk about it or admit it, but Angie told some friends that she had a 'mommy tuck'.

"She likes the way that sounds better than tummy tuck."

Over the weekend, Jolie took Manhattan by storm while in town to promote her new Clint Eastwood-directed movie, Changeling.

"Angelina looked drop-dead gorgeous in a tight black strapless Versace dress," says an onlooker who saw the actress attending the film's premiere at the Ziegfeld Theatre with Brad on Oct. 4. "My first reaction was, 'Holy cow, how did she get so thin after having twins?'"
