Bruno Mars will have help from the Red Hot Chili Peppers when he performs at the Super Bowl next month.
Mars announced that the Rock and Roll Hall of Famers will join him as part of his half-time show.
Super Bowl half-time performers often have collaborators.
Last year, Beyonce had Kelly Rowland and Michelle Williams from her Destiny's Child days join her on stage, and two years ago Nicki Minaj and M.I.A. joined Madonna for her half-time show.
Mars was named Billboard's 2013 artist of the year.
His hits include the No 1 song When I Was Your Man and his Grammy-nominated album Unorthodox Jukebox has sold almost 2 million copies.
