It was an interesting day at UCLA for AnnaLynne McCord -- who had to run through the quad in a bikini while students threw eggs at her!
It was all for the new season of "90210" and we're guessing is some kind of hazing ritual for the incoming freshman.
McCord, who looked beyond fit in her two-piece, was also attacked by water balloons -- all while making some pretty great faces.
It wasn't all bad for AnnaLynne though, as her new boyfriend Dominic Purcell also stopped by the set again.
The two made headlines earlier this week due to their age difference. McCord is 23, Purcell is 41.
