Washington, Mar 10: Hugh Hefner’s twin girlfriends, Karissa and Kristina Shannon, were refused the chance to donate their hair for charity, because their bleached blonde locks were ''too over-processed''.

The poor quality of the twins’ hair was revealed after 2008’s "Playmate of the Year" Jayde Nicole encouraged other playmates to donate their hair toward raising cancer awareness through her charity ‘Lengths for Love’.

London, February 4 : Nude Karissa and Kristina Shannon grabbed the spotlight at a Super Bowl party hosted by their boyfriend Playboy founder Hugh Hefner with their body paint.

Few guests were speculated to have realised the fact that the painted twin stunners were stripped to the waist.

They were each reported to have been adorned with body decorations, "sporting painted-on versions of bras and scanty alternatives to NFL-style strips", reports the Sun.
