The Dancing on Ice contestant, who was reportedly seen kissing ex-boyfriend Peter Andre recently, insisted that she doesn't think of the football player as "part of her life" anymore.
"It's got nothing to do with me. It's in the past, we've all moved on. I don't even think of him as part of my life. I'm looking for a new man," she told The Mirror.
Rivas admitted that she is more interested in tennis player Rafael Nadal than the father of her children.
"He is a fiery Spanish man with huge muscles. I'm going to Wimbledon to see him play and maybe I'll get to meet him. He's only 25 though, probably too young for me," the mum-of-two told the Daily Star.
Girls Aloud's Kimberley Walsh previously said that she doesn't think Rivas and Andre's five-month relationship was real.
