Five years since her last album, Kat DeLuna is back with a banger. The Dominican bombshell shakes things up on her steamy duet with Trey Songz, “Bum Bum.” Over a sample of Sister Nancy’s reggae anthem “Bam Bam,” she teases her man with her goodies (“Go hard but don’t break it”), while Trigga lays on the charm.

“I’m so excited for the world to hear my amazing new song ‘Bum Bum’ with the incredible Trey Songz,” said Kat. “This song is evidence that music transcends generations, and for that I want to specially thank Sister Nancy for originating such an incredible song that left its musical imprint culturally for years to come. I hope ‘Bum Bum’ becomes your summer anthem!”

Kat is working on the follow-up to 2010’s Inside Out for release later this year.
