Who knew Audrina Patridge was such a Comic-Con fan? The 29-year-old former reality star and 1stLook host hit the San Diego convention on Friday, July 25 in an impressive head-to-toe Mystique costume. 

Patridge showed her dedication by painting most of her body blue like the shape-shifting X-Men character, portrayed by Oscar winner Jennifer Lawrence in the most recent films and Rebecca Romijn in earlier installments. True to form, The Hills alum documented her shocking transformation on Instagram as a team of makeup artists worked to give her skin Mystique's unique texture and blue hue. 

Sporting a white outfit, cherry red wig, and lime green contacts, Lauren Conrad's former roommate looked confident posing amongst the other Comic-Con attendees, who also went all-out in fantasy-inspired costumes. 

Patridge participated in the event to help out makeup artist Cig Neutron, a season 7 contestant on The Face-Off

"check out #faceoff tonight on the sci fi channel @cigneutron is a contestant on it!! ..We are working together for @1stlooktv #ComicCon2014," the late night host tweeted prior to her makeover. 

After replacing Ali Fedotowsky on 1stLook this season, Patridge has filmed all over the country for the NYC-based travel show. It airs Saturday nights after Saturday Night Live
