"Happy Birthday Sebastian 'The Bash' Taylor Thomaz!!! Everyone welcome this perfect young man into the world," wrote proud papa Wiz Khalifa, whose real name is Cameron Jibril Thomaz, on Twitter.
Earlier in the month, Rose announced that she and Khalifa were planning on a natural birth at home, and that the decision was inspired by watching the documentary, "The Business of Being Born."
However, shortly before the birth, Khalifa released a photograph of himself wearing surgical scrubs, which suggests that the pair may have decided on a hospital delivery after all.
Rose documented most of her pregnancy through social media outlets, showing off pictures of her growing baby bump during each trimester.
The pair, who became engaged in March 2012, announced the news of their upcoming bundle of joy in September 2012.
Rose was previously in a relationship with rapper Kanye West, who is currently expecting his first child with model and television personality Kim Kardashian.
