The Smile singer fell out with The Roots star after he waded into the debate over her imitation of Beyonce at a gig in London last month (Apr14).
Many fans accused Allen of mocking the superstar by performing one of her songs during her set at the iconic G-A-Y nightclub, and Questlove responded by tweeting, "So Lily Allen is our cultural critic now? She'll soon be op-ed'ing for @EBONYMag (America's Ebony magazine) no?" prompting a sullen reply from the singer, who wrote to him, "I think you're being unfair. I love her and I love my fans who loved this performance, I wasn't critiquing, at all."
The pair was forced to put the feud behind them on Wednesday (14May14) when Allen was a guest on U.S. Tv's The Tonight Show Starring Jimmy Fallon, which features Questlove's The Roots as the house band.
Allen was surprised to discover a large bunch of white roses in her backstage dressing room with a note from Questlove which read, "At the end of the day Lily... I'm still a major fan of your's (sic). (Truce?) - Questlove."
The singer shared a picture of the flowers and note on her Twitter.com page, adding, "Too sweeeeet" with a symbol of a peace sign and an olive branch.
