Just a few hours after Wiz Khalifa announced it was "Daddy time" on Thursday, the rapper and his fiancee Amber Rose welcomed their first child.  They named the baby boy Sebastian Taylor Thomaz, according to Wiz's follow-up tweet.  

"Happy Birthday Sebastian 'The Bash' Taylor Thomaz!!!..." proud papa Wiz wrote, adding, "Everyone welcome this perfect young man into the world."

Amber had mentioned in interviews that she would do an all-natural water birth, but it looks like those plans changed.  A photo that Wiz shared showed him in blue scrubs, so perhaps the couple welcomed their son into the world at a hospital.
