That's right, it's Ray J's birthday and the singer/songwriter/producer/actor teams up with sis Brandy to celebrate it! The celebrity siblings are joined by their fearless posse on a private charter direct to Las Vegas.<br /><br />Of course, there'll be a lil' pitstop in Arizona to pick up some more friends ... and then it's champagne in the skies and a birthday blast to remember.<br /><br />Happy Birthday, Ray J!
