The typically camera-shy Olsen twins have been mugging more than usual lately. The reason? Supporting their younger sis (and newly crowned “It” girl) Elizabeth Olsen, star of the upcoming film “Martha Marcy May Marlene.”
On Tuesday night, Mary-Kate and Ashley hit up the premiere of the movie as well as the after-party at the Empire Hotel Rooftop.
“When Elizabeth arrived, the twins gave her a very long embrace,” a source told us.
At the party — also attended by a scruffy Jake Gyllenhaal and “Gossip Girl” star Chace Crawford — the three Olsens “held court at a corner table all night” and toasted Elizabeth’s movie with Bear Flag Wine, an eyewitness told us.
Though Elizabeth is quickly entering star territory, she hasn’t mastered one celebri-feat: wearing sky-high heels all night.
At the party, she “took off her very high heels and slipped on a pair of moccasins,” our source said. Gyllenhaal, meanwhile, also kept things casual, wearing cargo pants, a long-sleeve tee and glasses to the screening, then skipping the after-party.
“I don’t think anyone knew he was there,” the source said. “He clearly did not want to be seen.”
The twins also supported Elizabeth last week at a dinner, held at Lower East Side newbie Sons of Essex, celebrating the “Martha Marcy May Marlene” star’s Nylon magazine cover.
