Former Spice Girl, Melanie C, is fed up of seeing David Beckham in his underpants, though admits 'Brand Beckham' is "huge".

Melanie said: "When you see David in his pants quite a lot, you think, 'That's my friend's husband, and I really don't want to see him in his pants'.

"Brand Beckham is huge and they've worked so hard at building that huge empire. I see it all the time, the endless public fascination with them.

"I really feel for Victoria actually, because you can see whenever we meet up, she walks into a room and all eyes are on her. That’s a huge pressure.

"‘I think you make the decision quite early on to really nurture your profile and your relationship with the media. But the thing is, once you’ve done that it is done, and you can’t turn back."

Speaking candidly about the opening night of The Spice Girls' musical, 'Viva Forever', Melanie C said:

"We were disappointed that Victoria didn’t arrive with us on the red carpet at the premiere, I’m not going to lie.

"For her that evening was about her family, and that’s what she wanted to do. But we’re all grown-ups and we’ve been through so much.

"If somebody wants to do something a certain way, then we are not going to kick up a fuss about it.

"The rules of the Spice Girls are that we do really respect each other, and that’s all part of it. That’s what she wanted to do, so that’s what she did."
