Sandi Thom hits out at angry Allen

Sandi Thom has criticised Lily Allen for her recent volatile behaviour, advising the star to "get her s*** together".

The Scottish singer, best known for her chart-topping single 'I Wish I Was A Punk Rocker', revealed that she was shocked to see pictures of Allen lashing out at a woman outside a London nightclub last month.

Writing on her website, Thom admitted: "I can't believe Lily Allen hit that girl in the street, what the hell is that girl all about?"

"I can't believe she is slagging off Katy Perry as well, I am on Katy's side, I think she is great!" Sandi continued. "Lily must be too busy starting fights and slagging people off to write some new songs!"

Thom released her debut album Smile... It Confuses People in June 2006, one month before Lily's first LP hit shelves. She has since released a second album, The Pink and the Lily, but Allen's fans are still waiting for the follow-up to Alright, Still.

"I always expected her next album to be out the same time as me as both our first albums came out at the same time," she said. "But not a peep."
