'I don't even remember having sex' - Diplo's savage response to Katy Perry

Diplo has fired back at Katy Perry's jibe about his sexual prowess, saying he doesn't "even remember having sex" after she ranked him at the bottom of a list of ex-lovers.

The 'Roar' singer revealed the intimate rankings of exes Diplo, Orlando Bloom and John Mayer to James Corden during a 72-hour YouTube livestream on Sunday, in the lead-up to the release of her new album, Witness.

Diplo, who Perry dated briefly in 2014, was at the bottom of the list.

The DJ and producer took to twitter on Tuesday (local time) to respond a tweet from Vice.

 "I don't even remember having sex," he quipped.

He then shared a photo of himself on a pole above a crowd, adding, "I won the bronze medal in sex Olympics."
