It's finally happened! The world's longest pregnancy is at an end. 

Wiz Khalifa and Amber Rose welcomed their first child, son Sebastian Taylor Thomaz, on Thursday, February 21.

Wiz tweeted the happy news:

Amber recently teased intel on her son's name. "It’s not really a common name. It’s a normal name, it’s just not common.” She added that "[i]t's a total boss name for a boy." She also said Wiz had his rapper name picked out, and it sounds like it's "The Bash."

Welcome to the world, little Sebastian/The Bash! And congratulations to the happy couple. We've been waiting for this baby almost as long as they have. Now Amber can relax and stop hearing about how she's been preggers since time began.
