Lily Allen knows something about sabotage.

During the Monday, June 3 episode of her podcast Miss Me, which she hosts with best friend Miquita Oliver, the pop singer, 39, revealed that she once deliberately slept with her co-host’s celebrity crush.

The British TV presenter, 40, recalled a time when she interviewed a pop star in the early aughts that had a big album and she found out he “fancied” her.

“Careful who you tell things to — I told Lily that I liked him and she was like, ‘Well actually I like him,’ and I was like, ‘Well it doesn’t matter because he actually likes me,” Oliver said.

She explained that the “Smile” performer wasn’t a pop star then, but Allen — who was working artist relations at the time — went to a festival in Japan and “seduced him.”

When Oliver found out Allen slept with him, she said she had never been that “angry” with her friend.

“We did not speak for about six months,” the former The Month with Miquita host recalled.

But the “Alfie” musician maintained that she wasn’t trying to “sabotage” Oliver.

“I fancied him, so I was getting mine,” Allen said, adding: “By the way, I think pop stars are fair game, like, I don’t care.”

However, the TV personality felt that at the time she had been “sabotaged” by Allen.

“The point is we got over it,” Oliver said.

The singer-songwriter/actress then apologized saying she never wants to cause her friend “pain.”

“I actually thought you’d just be happy for me,” Allen admitted with a laugh.

In March, Allen — who shares daughters Ethel Mary, 12, and Marnie Rose, 11, with ex-husband Sam Cooper — opened up about how parenthood affected her career.

“My children ruined my career,” she said while laughing on the Radio Times Podcast.

Allen joked, “I love them and they complete me, but in terms of pop stardom, totally ruined it.”

“It really annoys me when people say you can have it all because, quite frankly, you can’t,” continued Allen, who married Stranger Things star David Harbour in Las Vegas in 2020.

While she acknowledges that “some people choose their career over their children, having absent parents herself “left some nasty scars” that she didn’t want to pass on to her kids.

“So I chose stepping back and concentrating on them and I’m glad that I have done that because I think they’re pretty well-rounded people,” Allen said. “Fingers f—ing crossed.”
