The Saturdays' Rochelle Wiseman has been enjoying spending time in Los Angeles recently, but was surprised this morning (October 25) to see a pictured of her bottom making its way around the internet.

The sexy singer, who is married to Marvin Humes from JLS, was photographed climbing to the top of an inflatable slide while wearing a short-skirted minidress and the images were published today much to her disapproval.

Upon seeing the set of photos, she took to her official Twitter page and revealed that she couldn't believe what she had seen, and added that there should be a law against printing personal photos in the public domain: "Just woken up to be greeted by pictures of my bum online! I'm SO embarrassed! Surely there's some sort of law against this? #barecheekofit"

Earlier this week, The Saturdays confirmed that they're working on a song with one of Lady Gaga's producers: "Can't believe we're in the studio with the LEGEND that is @RodneyJerkins!! Recording SUCH a massive tune for you all."
