Getting into exclusive nightclubs is no problem when you’re Lady Gaga (or even teen sensation Justin Bieber), but famewhoring Z-listers like Michael Lohan have a tough time getting on the other side of the velvet rope.

Despite sporting a tight shirt to accentuate his “bulging muscles” (Brain Bleach!), Lindsay Lohan’s headline-lovin’ pop — an alleged Born-Again Christian — couldn’t even crack the door at one of the newest lounges in Los Angeles, tabloid tipsters claim.

“Michael Lohan showed up to Industry in LA by himself on May 3 and was denied entrance,” an eyewitness cracked to Life & Style’s Scene Queens. “The doorman didn’t even know who he was!”

Is clubbing the most appropriate pastime for an almost 50-year-old man who’s made a career out of complaining about his famous daughter keeping late hours?
