Jasmine Waltz has described Celebrity Big Brother love rat Lee Ryan as a "100 per cent screw up."
The 31-year-old has spoken about her short-lived relationship with the Blue singer for the first time since dumping the star.
The former couple met on Celebrity Big Brother and were at the centre of a love triangle with glamour model Casey Batchelor on the reality TV show.
Waltz described the relationship with the 30-year-old saying: "He told me he loved me and wanted to marry me. But behind the candelabra everything about his life is bad.
"Being in a relationship with him was emotionally draining. Lee is a 100 per cent screw-up mentally. I couldn't get a word in edgeways as he talked about how his career was on the rise," the actress said.
The brunette beauty said Ryan was deluding himself about his band's success.
"Lee genuinely thinks Blue are Number 1 in the charts, are as big as One Direction and he has the appeal of Harry Styles. He cannot accept his career is going nowhere. It is tearing him apart and he needs to get help."
"He knows his career is pretty much over and he is lashing out. Blue know it is over. They want to keep touring, but have no label."
The Hollywood actress, who is alleged to have had an affair with Friends star Courtney Cox's ex-husband David Arquette, moved in with Ryan while she was staying in London.
The two also went on a luxury holiday to Thailand together.
A spokesman for the 30-year-old Blue singer responded to Waltz's comment saying: "Lee was kind enough to welcome Jasmine to stay at his home when she told him that she didn't have anywhere else to stay in the UK.
"Lee's first and foremost priority is the well being of his children and anything or anybody else comes secondary to that. Lee could not travel out to America as much as Jasmine would have liked him too due to his commitments in the UK.
"He hopes Jasmine finds what she is looking for and wishes her the greatest happiness and success in her aspiring acting career."
Waltz is said to have returned to Hollywood for a film shoot.
