Lily Allen's claws are out! The singer wasn't pulling any punches when she dressed in scrubs, a stethoscope and the name tag "Dr. Luke Gynecology Dept" on it. Ouch!

Earlier this month, Kesha made shocking allegations in a lawsuit claiming that the famed music producer Dr. Luke emotionally, sexually and physically abused her for 10 years. Dr. Luke has subsequently filed two lawsuits against Kesha's mother for defamation , asserting they were trying to extort him to get out of a record contract. Since the news hit, it's been a pretty sticky situation for both parties. Many artists have kept mum on the subject, refusing to take sides but -- it's pretty clear whose side the "F*ck You" singer is on!

Lily and Kesha have been friends for years -- so this definitely looks like a sign of support to us ...
