Comeback singer Britney Spears is reportedly furious after topless pictures of her have been leaked online. In the saucy shots, a grinning Spears poses outside, kneeling on a rock, while holding two flowers over her nipples.

And the singer is furious about the timing of the pictures - she has just embarked on a comeback trail, performing live in a series of comeback gigs this week in California.

A close pal of the singer tells British newspaper The Daily Star, "Britney's furious these photos have become public. She never dreamed they'd be leaked. She's concerned the photos will damage her credibility and just make her look trash

OK, so we're all clear on this, right? Britney didn't want these pictures out, get it? Especially with her concerts coming up. Britney has concerts coming up and she can't let anything effect her concerts. It's a damned shame that here she was, minding her own business in her back yard...with her juggs hanging out as most young mothers do...and some filthy lowlife paparazzi had to sneak up and take these candid pictures and them leak them, at a time when Britney is desperately trying to avoid publicity. A time when she needs to boost ticket sales.

To her concerts.
