Hockey WAG Hilary Duff at her day job

I wonder if Hilary Duff lets her hockey boy Mike Comrie come to the set of Gossip Girl when she is filming. I say that because lord knows if I was her I wouldn't let him near the place what with Leighton Meester, Blake Lively, et al prancing around there. It's rare when Hil is like third or fourth on the list of hot babes in the room, but on this set that might apply.
