Lily Allen showcased new material when she made a surprise appearance during Mark Ronson's gig on Monday night (24Oct16).
The Smile singer, who hasn't released new music since mid 2014, revealed she had been in the studio with the Uptown Funk producer, her longtime collaborator, when she appeared onstage with him for a surprise three-song set.
Introducing the British star to the stage at his intimate gig in London's Savoy Hotel, Mark called Lily the "person who gave me my big break 10 years ago" by hiring him to produce her 2006 album Alright, Still.
She performed Littlest Things from that record and confessed to the audience she hadn't performed in a while, saying, "I haven't played anything for about a year... Mark and I have been in the studio and were there last week."
Mark asked the crowd at his MasterCard Priceless Surprises gig if they wanted to hear a new song they've been working on and they performed the track, with Lily relying on a lyrics sheet placed on the floor, which she later had to pick up to read.
Lily ended her appearance with their 2007 cover of Kaiser Chiefs song Oh My God, which appeared on Mark's second album Version, and reportedly needed help remembering the lyrics again, according to the Press Association.
During his show, Mark was also joined by Andrew Wyatt from the band Miike Snow and American singer/songwriter Amanda Warner, who goes by the stage name MNDR. He performed hits such as Uptown Funk and closed the show with Valerie, his hit with the late Amy Winehouse.
Lily previously tweeted she would be letting her new music do the talking after she had been hit with rumours of a split from husband Sam Cooper, a new romance with rumoured boyfriend MC Meridian Dan, and allegations she passed out at London's Notting Hill Carnival from heavy drinking.
She came under fire earlier this month (Oct16) when she told a 13-year-old migrant in the refugee camp in Calais, France, “I apologise on behalf of my country for what we've put you through” and later confessed she could have worded her sentiment better.
