Ivana Trump wasn’t letting Finnish designer Ivana Helsinki leave the US without being served. Trump’s lawyer Gary Lyman hired a process server to crash the IVANAhelsinki fashion show on Thurs day with a summons and complaint for trademark in fringement of Trump’s name “Ivana.” The determined gumshoe was escorted out of Lincoln Center, so he fol lowed Helsinki to her after-party at Polar in the Marcel Hotel, where he waited outside from 10 p.m. till 2 a.m. to finally nail the designer. “Personal service is the best kind,” Lyman told us. “For all we knew, she could have left for Finland the next morning.”
