Attended by Kathy Griffin, New Kids on the Block singer Joey McIntyre and BSB's Kevin Richardson, Howie Dorough and Nick Carter, the couple's evening ceremony was held at the posh Beverly Hills Hotel, and officiated by celebrity photographer Tyler Shields.

Saturday's nuptials were a long time coming for the pair, who postponed saying "I do" when McLean checked into rehab for the third time earlier this year.
