Pregnant actress Jessica Alba is set to make some new enemies in Hollywood after criticising her contemporaries and even her own parents in a scathing new interview.

The Fantastic Four beauty, who is expecting her first child with fianc Cash Warren, told Elle magazine she has never used her stunning looks to land movie roles, despite her status as a sex symbol.

Alba's controversial comments came as she wigged out during a photo shoot in Los Angeles.

The mum-to-be held her small pregnancy bump in as she posed in a series of outfits and wigs for the shoot as she embarks on a publicity drive for her new movie The Eye.

The 26-year-old shows her disdain for teen Hollywood star Zac Efron and Latina actress Eva Mendes in the interview, and even criticises her Into the Blue co-star Paul Walker.

Despite being only six years older than 20-year-old High School Musical heart-throb Efron, Alba was unimpressed by the tween idol at the Teen Choice Awards last August, where they were named 'Hotties of the Year'.

She said: "He looks like a child with a lot of make-up. I was like, 'My God, you're just a little kid'."

Alba names herself alongside Halle Berry and Jennifer Lopez as the only non-white actresses who can open a movie.

When the journalist was quick to add Eva Mendes alongside the group, Alba fired back: "But is Mendes greenlighting movies?"
