Lily Allen admits to 'sabotaging' her friend by sleeping with her celebrity crush on purpose

Lily Allen has made the ruthless admission that she purposely slept with her best-friend's celebrity crush.

The 40-year-old pop singer has led quite the glamorous life since bursting onto the scene with her breakthrough single 'Smile' - including into the arms of her best mate's celebrity crush.

During an episode of her BBC Sounds podcast Miss Me? - which she co-hosts with her best friend Miquita Oliver - last month, the 39-year-old singer was called out by her friend for some seriously sneaky behaviour.

Miquita recalled how she had confessed to Lily that she had a crush on an early noughties pop star.

"I’d like to tell a story about when Lily Allen sabotaged me," she recalled.

"There was a pop star in the early noughties, I found out that he fancied me. I told Lily that I liked him."

Now usually when you find out your has feelings for someone you'd do your best efforts as a wingman in order to get them together - but not in this case, as Lily also fancied the singer.

Revealing Lily's response to the confession, the 40-year-old presenter said that she had replied: "Well actually, I like him," to which Miquita had replied: "Well, that doesn’t actually matter because he likes me."

Unfortunately this didn't stop the 'Not Fair' singer, as she soon jetted out to Japan and hooked up with the mystery man at a festival.

She continued: "Cue Lily, gets herself to a festival in Japan and seduces him. Seduced him with her wily ways."

"I flew to Japan to lock that one in," a mortified Lily replied.

Clearly Lily must have been feeling guilty the next day, as she called her friend to confess everything- and Miquita was not impressed.

Recalling her reaction to the confession, Miquita said that it was the angriest she'd been with her friend in her entire life, saying: "Did you think that you were sabotaging me in that act?"

Lily was quick to defend her actions, insisting that pop stars were 'fair game' and not off limits from friends.

"I fancied him, so I was getting mine. By the way, I think pop stars are fair game, like, I don’t care," she said.

Despite being fuming at the time, it's clear that the betrayal hasn't had a long lasting impact on their friendship, with Miquita admitting: "If I didn’t hate you so much for it, I would have applauded you. It was admirable."
