BACKSTREET BOYS - AJ MCLEAN STEPS OUT WITH PLAYMATE

BACKSTREET BOYS star AJ McLEAN is dating a PLAYBOY Playmate - despite declaring his commitment to patching up his on-off relationship with fiancee SARAH MARTIN.

McLean has been spotted all over Los Angeles with sexy model and fledging singer SUMMER ALTICE, 23, holding hands and acting very much like a couple.

But McLean's spokeswoman JULIET HARRIS insists, "AJ and Summer are really just good friends. He and Sarah are still trying to work things out."

McLean, 25, and Martin, 27, were supposed to be married on Valentine's Day (14FEB03). But the fairytale wedding was cancelled after AJ cheated on his belle.

Altice, who appeared in THE SCORPION KING, reportedly counts muscle-clad VIN DIESEL as one of her ex-loves.
