Look away now, J-Lo! Nicki Minaj and Casper Smart get close during music video shoot as he shows her some of his moves

She's been hard at work filming the music video for her new track The Night Is Still Young. And on Wednesday Nicki Minaj, 32, had a little helping hand from choreographer (and on-off boyfriend of Jennifer Lopez), Casper Smart. Nicki was seen shimmying in a super tight satin frock as Casper, 27, looked on - a sight that Jennifer, who has reportedly rekindled her romance with the dancer, may not be too happy to see.

It also comes months after the Super Bass hit maker was reportedly embroiled in a bitter feud with the American Idol judge.

According to Hollywood Life, J-Lo was seen sitting in the audience and scowling while the rest of the crowd bobbed their heads to Nicki's performance of Anaconda at a Fashion Rocks event in September.

It was rumoured at the time that the 45-year-old mother-of-two wasn't happy that Casper had choreographed much of Nicki's raunchy routine.
