(Cover) - EN Showbiz - Cameron Diaz likes to date head-strong males as they need to "out-alpha" her.

The Hollywood star is currently single after being romantically linked to a string of men over the years, including Justin Timberlake, Jared Leto and New York Yankees star Alex Rodriguez.

In an interview on UK TV series The Graham Norton Show, Cameron insisted she sometimes likes to be the "alpha female" in her relationships.

"It depends, but I do like an alpha man around to out-alpha me," she quipped.

Cameron is starring in What to Expect When You're Expecting as pregnant singer Jules. The blonde beauty wore a pair of faux breasts for the role and says although she loved having larger assets, they did pose some disadvantages.

"We were shooting in Atlanta and it was very hot and it got very swampy here [waving her hands around her boobs] and by the end of filming these beautiful breasts were literally hanging down to my waist," she joked.

"I was so upset but thought, Well that's nature, that's what's going to happen anyhow.'"

Cameron appeared alongside broadcaster and naturalist Sir David Attenborough on the show. The star was thrilled to come face-to-face with the 86-year-old star.

"I am so excited to meet you, because I wanted to be a zoologist. I thought I would be one for my entire life and I did end up studying animals, but human animals. As an actor that's what I do, but I find so many surprises when I watch your shows," she gushed.

David was playful with the 39-year-old and offered to "teach [her] all sorts of things", before Cameron teasingly responded: "Perhaps we could have a private viewing." (C) Cover Media
