Wiz Khalifa better take any tummy troubles elsewhere!

The rapper and his fiancée Amber Rose welcomed their first child, son Sebastian Taylor Thomaz, on Thursday, Feb. 21, the proud dad announced via Twitter.

“Happy Birthday!!!” Khalifa — born Cameron Thomaz — writes. “Everyone welcome this perfect young man into the world.”

After confirming the pregnancy while walking the MTV Video Music Awards’ red carpet in September, the couple posed for a series of intimate shots that showed off the model’s budding baby belly.

“I’ve decided that I’m going to have an all-natural water birth. No medicine,” the mom-to-be, 29, told XXL at the time. “I want those bragging rights! The next time Wiz has a stomachache … I’ll say, ‘I popped a baby out all natural!'”

It seems the couple’s son had other plans though, as Khalifa, 25, Tweeted a photo of himself dressed in hospital scrubs and a mask.

In January, Rose celebrated pending parenthood with a colorful baby shower surrounded by close family and friends.

Earlier this month the couple attended the Grammys, where Khalifa joked that he’d like his lady to “stay pregnant forever.”
