London: Singer Peter Andre is reportedly dating his ex-girlfriend Elen Rivas.

Andre, who split with Rivas in April, was spotted kissing her at the British reality telivision star Amy Childs` 21st birthday party in Soho in London.

"They certainly looked like a couple again. In fact, the word that evening was that they`re back as boyfriend and girlfriend. They looked in great spirits and completely loved up. There is clearly chemistry still there," quoted a source as saying.

"The kisses they were having looked quite steamy. Everyone was saying they must be an item again," the source added.
