After a lengthy separation, New Kids on the Block star Donnie Wahlberg and his wife Kim Fey are set to divorce.

Fey, who has cited irreconcilable differences as the reason for the split, is seeking sole custody of the couple's two children, 15-year-old Xavier and seven-year-old Elijah, with visitation rights for Wahlberg.

A representative for Wahlberg told People Magazine: "The couple has been separated for some time now and remain friends."

Wahlberg and Fey, who separated last January, have been married since August 1999.

But some split-ups do reconcile.

While Wahlberg’s marriage is kaput, he reunited with his band. New Kids on the Block, which sold 70 million albums in its heyday and inspired such boy bands as 'N SYNC and Backstreet Boys, broke up in 1994.

They got together this year and released a new CD called “The Block" and are on tour internationally.

With so many distractions, it is unlikely Wahlberg will be singing the blues.
