Wiz Khalifa and Amber Rose are finally parents. On Thursday February 21, Wiz shared the great news after his fiancee gave birth to their baby boy.

“Happy Birthday Sebastian "The Bash" Taylor Thomaz!!!” he wrote on Twitter. “Everyone welcome this perfect young man into the world.”

The 25-year-old rapper has been giving us a live countdown of the baby's birth since Tuesday, starting from pics on Instagram of a fetal monitor to Wiz wearing scrubs with the caption “Daddy Time.”

In our October/November 2012 cover story, Rose wanted to participate in an all-natural birth. "I'm so ready. I'm going all-natural. I've decided that I'm going to have an all-natural water birth. No medicine. I want those bragging rights," she said. "The next time Wiz has a stomachache or anything, I'll say, 'I popped out a baby all-natural.'"

With Sebastian to complete the Taylor Gang family, Wiz and Amber will be celebrating parenthood for a long time.

Congrats to the couple!
