Lee Ryan Blasts Jude Law for Cheating on Sienna Miller  7/26/05

British boy band star Lee Ryan has launched a scathing attack on Jude Law, declaring the actor "must be mad" to cheat on his fiancée Sienna Miller.

Last week (18JUL05), Law admitted he enjoyed a one-month affair with his former children's nanny Daisy Wright in America in March (05), only three months after his romantic Christmas Day (04) proposal to 23-year-old Miller.

Despite Law's claims the couple are "still engaged", Miller has been spotted without her engagement ring and was photographed cuddling up to her ex-flame Orlando Bloom at a polo match on Sunday (24JUL05).

Ryan enthuses, "I'm available if Sienna's up for it. She's a beautiful woman.

"Jude law must be mad to cheat on her. I'd never do that."
