Bieber, who has an estimated net worth of $300 million, shared a series of photos and videos from the pricey gig on Instagram Saturday, including a slideshow with the bride- and groom-to-be.

The singer smiled backstage in a white tank top, sagging black pants that showed his plaid boxers and a backward baseball cap as he posed with Ambani and Merchant, both 29, as well as their loved ones.

At one point in his performance, Bieber held out his microphone to front-row guest Orhan Awatramani, who bounced around while singing along to the Grammy winner’s 2015 EDM hit “Where Are Ü Now.”
