Migos rapper Offset took the stage with his bandmates at the Wells Fargo Center in Philadelphia to perform during Power 99’s Powerhouse concert Friday night.

But it was the Atlanta rapper's proposal to fellow emcee Cardi B that riled up the crowd the most.

While the artists, who were both on the show’s roster, were on stage, Offset dropped to one knee, presenting his girlfriend with an 8-carat diamond ring.

Cardi B jumped up and down in excitement while fans applauded wildly, and they cheered even louder when Offset stood to place the rock on his lady’s finger after she appeared to say yes.

The two, both 25, have been publicly dating since earlier this year.

Here’s a closeup of the bling:

It's been a good day for the couple. Earlier Friday, they released a new song together, along with Nicki Minaj, entitled "Motor Sport."

Now they’re celebrating their new music and their engagement. And supporters couldn’t be happier. Here’s how a few have been reacting on social media.
