Katie Price's ex-fiance Leandro Penna has moved on from their recent split.

The Argentinian model has been spotted kissing a mystery brunette less than one week after he split from the British glamour model.

The 27-year-old - who got engaged to the 34-year-old glamour model last April after dating for almost two years - was seen kissing his new lady in Miami, Florida as they enjoyed a day at the beach according to the Daily Mirror newspaper.

Last week Leandro claimed he finally had enough of life with ''crazy'' Katie and walked out on the 34-year-old because she was driving him ''insane''.

He told South American Caras magazine: ''I left her simply because she is crazy. Katie's brain is not wired right, or the wires don't connect properly.

''I don't know what's wrong with her. I was thinking it over recently and one day decided to pack my bags and leave.

''There was nothing else I could do. She was driving me insane.''

Leandro insisted he would never reunite with the twice divorced mother-of-three, despite reconciling after their previous split just eight months into their relationship.

He said: ''That's it, there's no going back. Katie is totally crazy. What started beautifully in February last year has now come to an end.''

His harsh comments are in stark contrast to Katie's statement last Tuesday (23.10.12) in which she said they had amicably parted ways after struggling to maintain their often long-distance relationship and wished him the best for the future.
