The Hills star posts EXTREME makeover snaps to Twitter!

The Hills star Audrina Patridge had a pretty epic makeover yesterday!

The 29-year-old reality TV star was at the Comic-Con convention in San Diego, and really got into the spirit with this amazing costume!

With head-to-toe blue body paint and a long bright red wig, Audrina dressed up as X-Men bad girl Mystique.

The character, a mutant shape-shifter, is known for her ability to transform into entirely different bodies and species.

Audrina shared a snap to Twitter captioned, 'And the transformation begins!!!' in the early hours of Friday morning. 

In the X-Men films, Mystique is played by actress Rebecca Romijn AND our very own Jennifer Lawrence!

10 out of 10 for effort Audrina!
