Presenting The Daring Issue in which Julia Roberts rocks!

To celebrate the actor's 50 birthday, Harper's Bazaar dedicated their cover to her. 

Dressed in a lovely pink layered gown, Julia is seen attempting to climb a rock. 

While we aren't sure if she managed to complete the task successfully, she did end up making a pretty cover star. 

Photographed by Alexi Lubomirski, the cover has been styled by Elizabeth Stewart.

For the second look, the actor rocked a black jumpsuit. 

One look at the cover and it's impossible to guess that Julia will turn 50 this week. 

Happy birthday in advance!
