Susan Boyle can add pop superstar Mariah Carey to her list of famous friends after the diva (Mariah, not Su-Bo) insisted she’s not surprised the Scottish singing sensation is freaked out by her sudden rise to stardom.

Boyle became an international star overnight when she showed off her singing skills on U.K. TV show Britain’s Got Talent, but the instant interest became too much for the spinster to handle – she checked into a mental health clinic after her final appearance on the show.

Carey, who herself suffered a physical and emotional breakdown in 2001, is far from surprised. She says, “I feel bad for her… We build people up so quickly now that of course it’s going to freak some people out. It’s difficult. It’s got to be tough.”
