We expat New Yorkers who rarely return to ground zero, always think of Liam McMullan (when we think of him) as the tiny adorable toddler who looked just like his mother Lori. Shockingly, he’s now a handsome 18 and looks just like his father, celeb photog Patrick. And, like his dad, he’s beginning to make the scene in and around “Page Six” (and none too soon, either). The troubled gossip sheet tells us today that Angela Janklow threw a party in New York to introduce her new mate Jeff Stein to her world (they didn’t already know by now?) and Liam was there, talking about his role in the movie Kid Cannibis.
