Not only did Little Mix perform their new song "Grown" at Tuesday's (Sept. 22) Apple Music Festival in London -- they also gave fans an acoustic snippet of their second Get Weird single, "Love Me Like You."

The ladies -- Jade, Perrie, Jesy and Leigh-Anne -- stormed onstage before One Direction's set with "Salute," complete with a full troupe of backup dancers. They launched into old favorites from their first two albums, like "Move," "Change Your Life," Wings" and "DNA."

When it came to "Grown," the ladies got fierce with the Jess Glynne-written song. They also teased Mixers with 17 seconds of their upcoming second single off their album, out Nov. 6 -- "Love Me Like You."

"Last night I lay in bed so blue/ 'Cause I realized the truth/ They can't love me like you," they sang. "I try to find somebody new/ Baby they ain't got a clue/ They can't love me like you."

They also sang "The End," the song Perrie Edwards broke down to when they attempted to perform it at their U.S. live stream. Perrie kicked off the song this time by shouting, "Who's excited for 1D?"
