Blonde bobber: There's barely any sign of a pregnancy bump

She said: "I'm proud of my heritage. That's all I know! I only know a Mexican-American upbringing. Nobody really knows what to do with me.

"I'm half Latin, but I grew up in the States, and I can't get roles playing a Latina because I don't speak Spanish.

"And I don't want to be the best friend, or the promiscuous girl, or the maid, because those stereotypes still exist with Latin roles. I want to be a leading lady."

Referring to a family holiday to Mexico's Yucatan Peninsula, Alba admitted she clashed with her parents over how to spend their time, with her mother and father opting to relax in popular bar chain Senor Frogs.

She said: "When I go to Mexico, I want to go to see the pyramids, to learn about the history... My parents want to go to Senor Frogs every day."

Alba also spoke of her excitement of becoming a mother; "I'm madly in love. I come from a huge family and I'm the oldest of 15 cousins, so I've known I've wanted kids.

"I'm ready to be a mum, and it's a really happy time for us and our families."
