"Happy Birthday Sebastian 'The Bash' Taylor Thomaz!" Wiz wrote on Twitter on Thursday. "Everyone welcome this perfect young man into the world."

Rose and Khalifa got engaged in March of 2012, and the couple announced her pregnancy at the 2012 MTV Video Music Awards last September.

In the October/November issue of XXL magazine, Rose said, "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. The next time Wiz has a stomachache or anything, I'll say, 'I popped out a baby all-natural.' "

Of course, this isn't a total surprise -- on Tuesday afternoon Khalifa posted picture of a fetal monitor with the caption, "Coming soon," and earlier today he posted the picture below and wrote "Daddy Time."
