Lily Allen is already regretting her latest tattoo. Both Lily and US actress Lindsay Lohan recently got "shhh..." tattooed on their index fingers after a drunken night partying in Los Angeles.

But Lily didn't realise she was actually a copying 'Umbrella' singer Rihanna, who had the design etched on last year. She said: "I've since found out Rihanna's got the same thing, so it's not really - I mean she's very cool - but I thought I was being original."?

Friends are saying Lily is a bad influence on Lindsay and the actress' girlfriend Samantha Ronson is regretting introducing the pair. Lily worked with Samantha's brother Mark on her debut album 'Alright, Still', and is good friends with them.

Sam recently played an acoustic show in Los Angeles and dedicated a song with lyrics about being "out of control" to Lindsay - leading to another in a long line of blazing rows between the couple.
