Justin Bieber performs and dances with Fan at the Billionaire Wedding Celebration

Justin Bieber put on a great show at his most recent concert… no, he’s not touring anymore – he performed at a ceremony for a billionaire’s wedding.

The singer-songwriter arrived in Mumbai yesterday Anant Ambani And Radhika trader‘s sangeet, a pre-wedding ceremony full of song and music… and instead of DJ, the couple brought the Biebs!

Check out the clip… JB gets down on the floor and dances by himself before pulling a girl up and spinning her around a few times for the audience.

By the way, there’s more video online too… with Justin singing classic songs like ‘Baby’ and getting the crowd dancing – definitely a wedding party these guests won’t soon forget.

Of course, the happy couple are currently known for having some of the world’s biggest stars in attendance… remember, in March, Rihanna performed at a pre-wedding ceremony for Merchant and Ambani – so the star power has remained high throughout the long pre-wedding.

As for Bieber… it’s a rare feat. Since then he has appeared sporadically on stage canceling his “Justice” tour after he revealed he was diagnosed with Ramsay Hunt syndrome.

His last major appearances were a guest spot at Coachella and a show during the NHL All-Star Game Weekend in Toronto… so only on the biggest stages will the man get the microphone live again.
