Hollywood stunner Eva Mendes has quashed rumours that she's pregnant, and maintains that she’ll make a terrible mother.

The 33-year-old claims that she’s tired of reports linking her to babies and marriage.

She says: "I don't wanna have kids... I love the little suckers; they're so cute but I love sleep so much and I worry about everything.

"I feel like the institution of marriage is a very archaic kinda thing. I don't think it fits in my world today."

The Ghost Rider star claims the latest pregnancy rumours came about after she put on a little weight: "I'm off season right now. I'm having the pasta, I'm having the dessert."
