Will Donnie Wahlberg's divorce give Mark Wahlberg cold feet?

Donnie Wahlberg and his wife, Kim Fey, are calling it quits. They both filed for divorce Aug. 13, according to court documents filed in Los Angeles and Ventura County.

Fey filed first, according to TMZ. So there. She cites irreconcilable differences and wants sole physical and legal custody of their two sons -- Xavier, 15, and Elijah, 7. Wahlberg would get visitation.

Fey, 39, wants spousal support and attorney's fees from the former New Kids on the Block singer, also 39. They've been married since 1999 but separated in January.

A rep for Wahlberg told People, "The couple has been separated for some time now and remain friends."

So why do we care, you're wondering? Because of what Donnie's big D might do to his brother Mark Wahlberg's marriage plans, that's why.

Mark is said to be finally thinking about tying the knot with longtime girlfriend Rhea Durham, the mother of his two young children, after she pops out baby No. 3 in September.

This could put a real crimp in their nuptials. Wanna bet Markie Mark's feet get really cold again?
