Emmy Rossum is a good friend.

According to Page Six, the 29-year-old actress blew into New York City to lend a helping hand to her childhood friend Dorie Golkin Smith.

Emmy Rossum’s friend is co-owner of new Flatiron clothing shop Of Mercer and Rossum made a quick trip to the big city to help her friend get ready for her store’s opening last week.

“[Emmy] painted the walls of the store — the doors — everything that needed finishing,” said a source. “She went methodically through each letter on the sign with a Q-tip to make sure it was neat.”

If there are angels in heaven, they just got a little prettier… because Jake is up there painting their faces… putting lashes on them…
