Champagne and cigars for everyone! Congrats to 'Black and Yellow' rapper Wiz Khalifa.

His fiancée, model Amber Rose, gave birth to their first child, a son they've named Sebastian 'The Bash' Taylor Thomaz. That's quite a moniker, isn't it?

The infant was born Thursday, February 21.

The proud papa tweeted to announce the good news, writing, "Happy Birthday Sebastian “The Bash” Taylor Thomaz!!! Everyone welcome this perfect young man into the world.”
