A day after estranged husband [artist id="1000"]Nas[/artist] broke the news of the birth of the couple's first child, [artist id="509603"]Kelis[/artist] officially announced the delivery of Knight Jones. "Kelis gave birth to Knight Jones last night on July 22nd around 9p.m.," a statement from Kelis' spokesperson read. "Weighing a healthy 7.8 lbs, the beautiful baby boy and his mother are doing wonderful."

The statement noted that the birth was natural and that Kelis went into labor around 2 a.m. on Monday morning. The singer's first child was delivered at a New York City hospital with her mother and sister in the room.

In a video posted online Wednesday, proud papa Nas spilled the first details of the birth. "My son is born today, so shout-out to my son, Knight," the rapper says in a clip, which is stamped with Tuesday's date. "My son's name is Knight. That's what I named the young God, Knight," Nas tells fans in the clip. "Y'all heard it first. Don't believe nothing you hear in the media. I love y'all. Don't listen to that bullsh--. I love y'all, that's why I'm here."

The couple [article id="1602698"]publicly announced the pregnancy[/article] in January after being married for four years.They appeared to be in good spirits months after the announcement as they solicited names for their child from MTVNews.com readers. However, just two weeks after the solicitations, Kelis unexpectedly [article id="1610426"]filed for divorce[/article] from her husband. The splitting process has been bitter, with the two [article id="1614077"]arguing over finances in court filings[/article]. At one point Kelis [article id="1613319"]took to Twitter to admonish Nas[/article] after the rapper posted a salacious picture of himself with a group of women on the site using singer Maxwell's account. Reports also surfaced on Tuesday that Kelis barred Nas from the delivery room while she was in labor and her delivery announcement appeared to confirm that.

While the once happily married couple continue to be at odds, Nas appears to be in a celebratory mood over the birth of his second child in the online video. (He also has a daughter from a previous relationship.) In the same video clip, taken at a neighborhood party at the rapper's native Queensbridge Housing Projects, Nas takes the stage to perform. He again shouts-out his son and also urges his fans to be cautious when watching news reports about his divorce proceedings.
