Pop star Kesha joined Renee Rapp on stage in a surprise performance at Coachella.
Mean Girls actress and singer Rapp brought on 37-year-old Kesha to duet on her 2009 debut track Tik Tok at the Outdoor Stage on the final day of the Californian music festival.
Kesha, who wore a t-shirt which read “I am mother” paired with denim shorts and white cowboy boots, was pictured at the Neon Carnival after-party in Palm Springs a day earlier, alongside US star Paris Hilton.
Rapp, who starred as Regina George in the Broadway musical of Mean Girls before landing a role in the film’s remake, left her regular role in The Sex Lives of College Girls to release her debut album Snow Angel last year.
