Celebrity photographer Patrick McMullan’s son Liam, whom we knew as a toddler and recently met up with again at a party in New York where he talked to us briefly in a British accent, is getting married. The 21-year-old man-about-Manhattan has become engaged to 35-year-old aspiring actress Aesha Waks from Rockaway Beach, whom he’s known for a month. “Yep, I’m in love; I found my soulmate,” he confessed to Guest of a Guest. In lieu of an engagement ring, they’ve had each other’s name inked on their upper arms. Both daddies are OK with the cougar-cub engagement. “He hasn’t known her long,” senior McMullan told Page Six, “but I’m open-minded about it. I’m not happy about the tattoo, though; it makes me crazy. I told him they should just get a spiritual marriage, instead of a legal one.” Because anyone who knows Patrick knows he’s nothing if not spiritual.
