London: Backstreet boy singer AJ McLean married his longtime girlfriend, Rochelle Karidis, on Saturday in Los Angeles.

The couple have been dating for a long time and exchanged vows in a back garden of a hotel which was decorated with white rose petals.

Walking down the aisle in a Vera Wang gown to the tune of Guns N' Roses' 'November Rain', Karidis said her vows to McLean.

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

The duo had previously postponed their nuptials because McLean checked into rehab for the third time earlier this year.

The singer, who proposed to his girlfriend on his 32nd birthday in January 2010 during a live concert performance in Las Vegas, credits his new bride with encouraging his sobriety.

"I really miss and love Rochelle. You are my whole world and I cannot wait to spend my life with you. Without you here, I am lost," McLean tweeted.
