The tongue-lashing Lily Allen has blasted Britain’s Got Talent star Susan Boyle after a victorious performance on last weekend’s show, labeling the Scottish spinster turned YouTube sensation “overrated.”

The “Smile” singer was less than impressed with Susan’ rendition of the showstopper “Memory,” featured in the musical Cats. The weekend performance won Susan a spot on BGT’s May 30 finale.

“I thought her timing was off on Sunday – no control, and I don’t think she has an amazing voice,” Lily wrote on her Twitter.com page Monday.

Lily claims 12-year-old Shaheen Jarfagholi is far more talented than the 48-year-old Boyle and should have advanced to the finals.

“She can sing, but it’s not about talent with her, is it? She seems like a lovely lady but, if the show is about talent, then that Shaheen kid should win,” she added.

We’d like to hear your opinion: Do you agree with Lily? Is Susan Boyle’s talent overrated?
