Young Thug Proposes to Mariah the Scientist During Atlanta Concert

Congrats are in order for Mariah the Scientist and Young Thug — they’re engaged!

The “Go Crazy” rapper popped the question to his longtime girlfriend on stage at his “Hometown Hero: Young Thug & Friends” benefit concert in Atlanta last night — and it’s all on video! Check out the adorable moment … he’s on one knee as he pulls out a massive diamond ring with a huge grin across his face. The words “Will You Marry Me” are also displayed on the giant screen on stage.

It was a no-brainer for Mariah, who let him slide the sparkler onto her wedding finger. She’s clearly thrilled, saying into the mic … “Guess I’m getting married!” as fans go ballistic in the venue. The moment is sealed off with a kiss.

It’s no secret Mariah had her heart set on walking down the aisle with Young Thug. She said during an interview just a few days ago with Power 105.1 she’s ready to “settle down” and eventually, have a child.
