Elizabeth Olsen says Ashley Olsen is her favorite sister

LOS ANGELES, Feb. 20 (UPI) -- Elizabeth Olsen, the Olsen twins' younger sister, was asked to pick her favorite sister while appearing in Watch What Happens Live Wednesday. In spite her better judgement, the actress gave an honest answer she later came to regret.

It all began when a fan called into the Bravo show and asked Elizabeth which of her sisters she liked better, Mary Kate or Ashley Olsen.

"Now this is a good question," host Andy Cohen said. "There has to be one that is more in your favor today that you're more vibing on."

"Ashley remembered my birthday, but I don't hold grudges against Mary-Kate forgetting mine," Elizabeth responded. "She was out of town! I should have just said my brother!"

"You are though, to clarify, feeling closer to Ashley today," Cohen joked.

"We're all very close!" Elizabeth, who turned 25 on Sunday, added. "I'm very close with my brother [Trent, 29] as well. I should have just said him. That would have been the easier scapegoat."

"Mary-Kate is literally going to come home from her vacation and shoot me that I said that," the In Secret actress joked, adding that nobody check the date when they're on vacation.

"You're just like, 'This is day three of my vacation,'" she quipped.
