Victoria Beckham won't do a triathlon because she would hate to get her hair wet.

While her close pals Tana and Gordon Ramsay are big fans of the multiple-stage competition including cycling, swimming and running, super-fit Victoria has ruled herself out.

Tana told Stella magazine: "Victoria is really fit but I couldn't get her to do a triathlon because she's never want to do the swimming and get her hair wet all the time. She'd be the first to admit that."

Some people have commented that Tana is turning into a clone of her pal after straightening her hair and adopting a new sleeker style, and Tana insists the pair laugh about it.

She said: "We both laugh our heads off about it. I don't actually think I look like her. Yes, my hair has gone straighter because those curls have dropped out but it's still wavy. And she will say 'you have to get these shoes, they are amazing'. And I'll do what she says. I take it as a huge compliment but we're very different.

"For the most part we are friends because we have four kids the same age, really busy lives and the best times we have are on family holidays when it's nothing smart or fancy, just hanging around in shorts and T-shirts with the kids."
