Congratulations to Backstreet Boys singer A.J. McLean, who wed his longtime girlfriend Rochelle Karidis over the weekend!

McLean and Karidis exchanged vows on Saturday (Dec. 17) in Los Angeles at the posh Beverly Hills Hotel, surrounded by their family and friends, according to Us Weekly. Some famous faces who attended the ceremony of the singer included Kathy Griffin, New Kids on the Block singer Joey McIntyre and McLean's fellow Backstreet Boys members -- Kevin Richardson, Howie Dorough, Brian Littrell and Nick Carter. Celebrity photographer Tyler Shields officiated the ceremony.

Karidis, who walked down the aisle to Guns N' Roses' 'November Rain, wore a beautiful Vera Wang gown. The happy couple then said "I do" under a tent in the hotel's back garden, which was filled with white rose petals.

McLean popped the question to Kardis in January of 2010 -- on his 32nd birthday -- during a live performance in Las Vegas. McLean, who checked into rehab for the third time earlier this year, credits his new bride for saving his life and keeping him sober. "I really miss and love [Rochelle]," McLean recently tweeted to his then-fiance. "You are my whole world and I cannot wait to spend my life with you. Without you here, I am lost!"

So sweet! Congratulations to the happy couple from all of us here at PopCrush!
