The already thin and petite actress looks like she has lost even more weight — has she gone too far?

January Jones, star of Mad Men and the upcoming X-Men : First Class, made an appearance at a dinner party for designer Donatella Versace in London on Nov. 11, and the already thin actress looks like she has lost even more weight! January, who is dating Saturday Night Live funny man Jason Sudekis and was previously linked to Ashton Kutcher, has always been tiny but it seems like she may have gone too far!

What do you think HollywoodLifers, is January scary skinny or does she look healthy?
