The NY Post reports that the Olsen twins are just not getting along these days.

Apparently, Mary-Kate and Ashley are doing all their in-person meetings (for their clothing line, Elizabeth and James) separately. "Something happened between them, and they haven't worked it out," a source says. "It's been going on for a while."

Last time we saw the duo together was at the Costume Institute's Gala at the Met in early May... and they looked perfectly happy and bubbly together.

I don't think I can go on knowing the Olsen twins are fighting - work it out, girls!
