Former Sugababes star Siobhan Donaghy has wed her longtime boyfriend Chris Mccoy.

The pop star, 28, and her sailor beau exchanged vows on Thursday (17Jan13).

The wedding news was confirmed by Donaghy's bandmate Keisha Buchanan, who posted a shot from the nuptials on Instagram hours after the intimate ceremony.

Buchanan, who is now the new bride's bandmate in Sugababes spin-off band Mks, wrote, "The most beautiful bride I've ever seen! Siobhan I'm so proud of u, Love u 2 bits! Chris ur amazing! Mr & Mrs MCCoy!"

The wedding comes just two weeks after Mks performed their first gig together for almost a decade on New Year's Eve (31Dec12). The former Sugababes reunited last year (12).
