Demi Lovato took an embarrassing dive on a slippery stage in Los Angeles on Sunday (05Jul15) as she celebrated the release of her new song Cool For The Summer with fans.

The pop star is hitting a number of fan pool parties to perform the track live, but her latest 102.7 Kiis FM bash left her a little red-faced as she took a tumble before jumping into the water outside an apartment block in L.A.

The singer was walking across the stage in a one-piece swimming costume and sarong when she slipped and fell.

She later addressed the embarrassing moment on Twitter, writing, “Well… It’s not a tour without busting a**!!!!!! NOT cool for the summer.”

The singer also posted video footage of the incident and added the caption, “NOT cool for the summer… F**k it”.

Lovato’s pool party tour began last week (ends05Jul15) when she celebrated with fans on the roof of the Gansevoort Park Avenue hotel in New York City.
