The Young Money family just got a little bigger. Tyga and girlfriend Blac Chyna welcomed their first child, a boy named King Cairo Stevenson.

The baby was born on Tuesday in Los Angeles and weighed 7 lbs., 1 oz. The new father shared his happiness with his Twitter followers. “Most Amazing feeling ever,” he tweeted along with a photo of him holding his new bundle of joy.

“Welcome King Cairo Stevenson 7lbs 1 oz ……. #blessed !!!!” wrote King Cairo’s mother. “40 long weeks …. So happy words can’t explain !!!”

The couple was rumored to be engaged earlier this year, but Tyga squashed the reports. Blac Chyna stars alongside Tyga in the “Rack City” music video.

The 22-year-old rapper will head out on the road with Nicki Minaj later this month and just purchased a new mansion in Calabasas, Calif., for his new family.
