Teaming up for a sisterly night on the town, Mary Kate and Ashley Olsen turned up for a tribute to Tim Burton at The Museum of Modern Art in New York City on Tuesday night.

The former “Full House” stars both brought their unique styles, sticking side-by-side as they mingled with a guest list including, Johnny Depp, Brooke Shields and Ashley Greene, among many others.

As for work duties, the Olsen gals have been busy with their new line for JC Penney called Olsenboye – which is a cheaper alternative to their other offerings.

According to previous reports, Mary-Kate emphasized that the duo “felt strongly about creating a unique experience to reach the teen customer, using relevant marketing strategies that would effectively reach this key customer demographic.”

Lance Armstrong says, despite his daughter taking Ashley Olsen to show and tell the other day, “Ashley Olsen and I are strictly friends. We have hung out amongst other friends , and she strikes me as a nice, smart lady. Sheryl Crow was reportedly unhappy about Lance and Ashley dating. She said on her blog, “Lance and I are friends. I have a lot of respect for him and what he does in the world of cancer. What he does in his personal life … is none of my business. Nor would I ever comment on it. The age difference alone between Lance and Ashley makes it unlikely they would ever seriously date. Sleep together maybe, but nothing more than that.
