Carey's ex "heartbroken" over marriage

Mariah Carey's ex-boyfriend Mark Sudack is reportedly "heartbroken" over the singer's marriage to Nick Cannon.

Music producer Sudack, who worked on Carey's latest album E=MC², started dating the singer in 2004 but was dumped at the start of the year.

An insider told Us Weekly: "Everyone is scared to call him because no one knows what to say.

"He never thought she would go off and marry someone else. He's heartbroken and shocked."

Carey and Cannon have allegedly clashed over plans to start a family.
