Looks like Nikki Blonsky has plenty to sing about: The Hairspray
star has a new boyfriend, aspiring model/actor Tommy Potoeski, a source confirms to PEOPLE.
The actress, 22, stepped out with her new man, 25, Monday, sharing a kiss on the streets of New York.
Their evening, however, was a family affair
, as the couple helped Blonsky's parents, Karen and Carl
, celebrate their 23rd wedding anniversary at Manhattan restaurant APL.
The party dined for four hours, capping off their meal with an oversized cupcake from Crumbs bakery and a customized cake baked by restaurant owner Joey Verdone.
