The Backstreet Boy singer and his bride tied the knot on Saturday.
The wedding was held at the Beverly Hills Hotel and was officiated by celebrity photographer Tyler Shields.
Guests at the ceremony included Kathy Griffin, New Kids on the Block singer Joey McIntyre and McLean’s fellow bandmates Kevin Richardson, Howie Dorough, Brian Littrell and Nick Carter.
The event unfolded under a tent in the hotel’s back garden, which was filled with white hydrangea and rose petals. After the ceremony, the guests moved into the hotel’s Crystal ballroom for dinner and dancing.
The bride wore a Vera Wang gown and walked down the asile to the tune of Guns N’ Roses’ “November Rain.”

The singer took to Twitter on Friday to express his excitement, writing, “Wedding is tomorrow, Ro and I could barely sleep last night, I think we’re a little excited!
“I’m so nervous and excited for tomorrow,” he added.
AJ popped the question to Rochelle back in January 2010 while celebrating his 32nd birthday in Las Vegas.
Initially, the nuptials were planned for May, but McLean had to check into rehab earlier this year to seek treatment “for personal reasons”, forcing the couple to postpone the wedding.
AJ is grateful to his new wife for helping him fight his addiction.
“I really miss and love [Rochelle]. You are my whole world and I cannot wait to spend my life with you,” he recently tweeted. “Without you here, I am lost!”
