A New Kid on the Block is officially gonna be hangin' tough by himself for a while, because his wife has filed for the big D. And we got footage of the dude celebrating this weekend at JET nightclub in Las Vegas.
Donnie Wahlberg's wife of eight years, Kim Fey, filed for divorce in L.A. County Superior Court. They have two kids, ages 7 and 15.
She cites irreconcilable differences. She's asking for sole custody, giving him visitation. She also wants spousal support.
The couple separated last January.
UPDATE: A rep for D. Berg called to say he filed against her first in Ventura County ... so THERE!
