Wiz Khalifa and Amber Rose's baby boy was introduced to the world on Twitter this week in a rather nice father-son snap that saw rapper Wiz cradling his kid in the hospital, hours after Amber had given birth. The snap, featuring Khalifa in a fetching pink hoodie, included the caption, "Best daddy ever.. Up with the baby so Muva can go back to sleep :-)

The new mother was understandably head over heels with the new addition to the family, tweeting earlier, "Happy Birthday to our baby boy Sebastian 'The Bash' Taylor Thomaz! I'm so happy u guys I fell in love all over again! :-)" There it is. The all-important name, and a pretty cool one at that. Sebastian Taylor Thomaz. It's got Grammy Awards written all over it. There's been some pretty bad celebrity baby names over the past couple of months - Sirus, Tennessee, Olive, Gavin, Camden-John - and we think Sebastian stands up pretty well.

The congratulatory messages began pouring in from Wiz and Amber's famous friends almost immediately after the birth. "Congratulations to my fam @mistercap and @muvarosebud !!! Welcome baby Bash! You're born in an exquisite month #babypisces," tweeted Rihanna. "Welcome 2 fatherhood @mistercap!!! Congrats 2 u n @muvarosebud on ur new son - he got the same Cday as @cbroadus!!! Bless up," said Snoop Dogg, referring to his own son Cordell.
