Madonna will be making an appearance at Britney Spears' summer tour ... or at least one of her songs will.

Britney, who kicks off her tour next week with Nicki Minaj, will be singing Madge's 1983 song "Burning Up" -- and a studio version of her recording found its way online today.

This isn't the first time Britney and Madonna have crossed paths. The two famously kissed during the 2003 Video Music Awards, Madonna was featured on Brit's 2003 single "Me Against the Music" and Spears popped up for a duet during one of Madge's 2008 concerts.
