Working on the follow-up to 2010’s Inside Out, Kat DeLuna returns with a certified banger. The Dominican vixen fires off a steamy duet with Trey Songz titled, “Bum Bum.” With artwork to make the fellas and ladies look for a fan to cool off, the singer samples Sister Nancy’s reggae record “Bam Bam.”

Teasing her man with her obvious goodies, Trigga Trey lays on the charm with his own sex appeal.

“I’m so excited for the world to hear my amazing new song ‘Bum Bum’ with the incredible Trey Songz,” Kat said. “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!”
