Jennifer Lopez's boytoy is probably having a gay old time being attached to the super-successful singer and ex-American Idol judge. But if something seems queer about the situation other than their age difference, there may be a reason. It was reported a week or so ago that Casper Smart was shopping at a sex shop for some naughty gifts for his girlfriend's birthday. However, sources say he wasn't there to buy gifts - at least, not for her. Radaronline.com reports that a regular at the 24-hour peepshow next door saw Smart enter the show, not the adjoining shop. And he was photographed leaving without any bags, packages or anything indicating he'd purchased anything. An undercover Star reporter talked to a man "familiar with the spot," who told him, "This is a gay cruising spot. You go into the booths, then you get all kind of tapping on the wall and propositions. It's like zombies." Another peepshow regular told Star when shown a photo of Casper, "Yeah, I've seen him. He was in here about three weeks ago." It's not the first time for Smart at the gay rumor rodeo. His Step Up 3D costar Joshua Lee Ayers tweeted a provocative photo of Smart back in June, urging viewers to check out Smart's "low key homo ways." Mark Young, mouthpiece for both Lopez and Smart, denied the allegations: "Casper is not gay. These comments are born from envy and jealousy."
