Christiane Shillito, known professionally as Ulorin Vex and Malady Charlotina, is an English alternative model and illustrator based in Los Angeles, California.

Her extensive list of credits include dozens of magazine features and covers, ad campaigns, billboards, and spans all genres from fashion to fetish and art nudes.

Vex began to branch out into more mainstream modeling work in 2008 when she was featured in two global ad campaigns for TIGI bedhead, including several hair magazine covers and billboards.

Her artwork was featured along with an interview in issue 176 of Bizarre (June 2011) which highlights the difference between the confident "vixen-esque beauties" of her illustrations and modeling images with someone who is actually "softly-spoken and shy in the flesh".

She also cites being influenced by artists including Egon Schiele, Hans Belmer, Michael Kaluta and the fierce female characters of Olivia De Berardinis.
