Jennifer Lopez was the headliner at a lavish wedding for a billionaire couple in India — and one of the guests was none other than Donald Trump Jr. — who was seen bustin’ some moves on the dance floor.

Check out video from Friday’s big 3-day, 007-inspired wedding event, which shows J Lo hitting the stage to perform some of her biggest hits in front of the rich and famous, mostly from Bollywood.

J Lo wasn’t the only one tearin’ up the dance floor. Don Jr. and his squeeze Bettina Anderson also let loose, swiveling their hips to Bollywood music. Other notables included Bollywood actor Ram Charan — known in America for his work in “RRR” — British singer Sophie Choudry and Canadian actress Nora Fatehi.

In addition to J Lo’s high-octane performance … guests were treated to the wedding ceremony and a 15-foot wedding cake in the shape of a palace. Pharma company heir Netra Mantena tied the knot with tech entrepreneur Vamsi Gadiraju near the Taj Lake Palace in Udaipur — a spot popularly featured in the 1983 Bond flick, “Octopussy.”
