Glamour

Britney looks stunning in a feathered Matthew Williamson frock on the October cover of UK's Glamour mag -- she's definitely back!

The "Hold It Against Me" singer posed for a sexy spread which features her hotness between the sheets (as well as a sexy full-length lingerie shot) which puts her perfectly tanned and toned bod on full display.

The Princess of Pop gave Glamour an intimate interview in which she gives details on her London tour (will she meet William and Kate?) and how she feels about turning the big 3-0 in December.

Brit expressed on the possibility of Prince William and Kate Middleton attending one of her concerts at O2 arena in London:

"That would be amazing. That would be really crazy and cool. I think they’re a beautiful couple. Unfortunately I didn’t get to watch the wedding but I heard it was beautiful."

The "Femme Fatale" singer also opened up on hoping to get more intelligent as her 30th birthday approaches, revealing:

"I think the older you get, the wiser you get. I can’t wait. I’m really excited and definitely gonna celebrate and do something spectacular. I’m gonna be in South America so I’ll have to do something pretty fun. A carnival of Britney?"

Britney's Glamour UK cover is set to hit newsstands Thursday, Sept. 8.
