We’re okay with admitting that we have a pretty substantial girl crush on MTV Canada’s Jessi Cruickshank. It’s no big deal or anything, she’s just really beautiful, funny and well-dressed, and super-cool. But now our girl crush is being stepped up to a whole new level, because Jessi is doing some really great philanthropic work with Free the Children and cast members from The Hills.

Along with Lauren Conrad, Audrina Partridge, Whitney Port and Lo Bosworth, Jessi is donating her vintage and designer gowns for the charity event THIS IS MY DRESS, to be auctioned off with all proceeds going to Free the Children. The gowns, which will be auctioned on eBay, will be available for bidding tomorrow.

Jessi has been involved with Free the Children since she was only 12 years old, and enlisted her Hills friends to participate in the fundraiser. She recently traveled to Kenya to shoot an MTV documentary on Free The Children’s school-building projects there but got this event together before she left.
