They always say that honesty is the best policy!
During a guest appearance on Bravo's Watch What Happens Live, Elizabeth Olsen admitted to Andy Cohen that she does in fact favor one of her famous sisters.
"Ashley remembered my birthday, but I don't hold grudges against Mary-Kate for forgetting mine," she revealed on the late-night talk show.
But Elizabeth, who turned 25 on Sunday, defended her sister's forgetfulness.
"She was out of town! I should have just said my brother!"
Cohen joked, "Ashley's in the lead today, but tomorrow M.K. could do something amazing."
"We're all very close," the In Secret actress explained. "I'm very close with my brother [Trent] 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," Elizabeth added, after revealing that her older sister is currently in Jamaica getting some much needed rest and relaxation.
"How often when you're on vacation do you look at your phone and read the date?" she asked Cohen.
"You don't really read the date. You're just like, 'This is day three of my vacation.'"
It sounds like Mary-Kate doesn't have that much explaining to do!
