Julia Roberts thought she was the prettiest

Los Angeles - Julia Roberts used to think she was prettier than Halle Berry.

The August: Osage County star admits she used to be very competitive with other actresses, but believes it was a ''godsend'' that she was never won accolades or titles for her appearance because it helped her to stay grounded.

The 46-year-old star told the September issue of InStyle magazine: ''I think I've always sort of been on the more boyish spectrum of girls. For example, I've never been chosen as 'one of the top-five hottest actresses in a bikini'. And honestly, it's a godsend.

"When I was younger, I'd think, 'Oh, I'm the prettiest one. It's not Halle Berry. It's not!' But it is, you know?''

The Oscar-winning actress, who has 9-year-old twins, Hazel and Phinneaus, and 7-year-old son Henry with husband Danny Moder, insists that her life isn't glamorous away from the spotlight and she still struggles to juggle everything.

Explaining why she hates being asked, ''How do you do it all?'' she said: ''Because, (a) I'm not nearly as busy as people think, (b) half of everything just doesn't get done - as long as no one is in tears, nobody smells bad and everyone's sleeping peacefully, I've done my job - and (c) I have a supportive group of girlfriends, a great husband and an understanding family.

"The rest gets done with grit, spit and a whole lot of duct tape.''
