Former New Kids on the Block singer Jordan Knight and his wife, Evelyn, have welcomed a son, Knight confirms to PEOPLE exclusively.
Eric Jacob Knight weighed 7 pounds, five ounces when he was born in Boston on Wednesday night, after an intense labor. "I can't believe the strength of my wife," Knight, 36, tells PEOPLE. "Now that the intense emotions have passed, I'm walking around on cloud nine!"
Perhaps the most excited family member was the Knight's older son, Dante Jordan, 7. "He wouldn't sleep for a day and a half until he saw his baby brother," says Knight. "He was priceless."
In late 2006, Knight released his second solo album, Love Songs, which includes covers of classic ballads. His previous self-titled solo album was certified gold. In addition to his music, Knight has found a home in reality television, with appearances on The Surreal Life and The Surreal Life Fame Games.
For now, he's taking some time off to be with his growing family. And, he says, don't be surprised if Eric grows up to be a heartthrob: "Watch out – he's a looker!"
