Kayla Collins — Babe of the Day

Kayla is a 26-year-old Playboy model, actress and entrepreneur.

You might recognize Kayla from E!'s 'The Girls Next Door' or her August 2008 Playboy centerfold, for which she was personally recruited by Hugh Hefner’s ex Holly Madison.

In addition to her regular appearance in magazines, commercials, on film and TV, Kayla has done promotional work for the likes of Jack Daniels, Mini Cooper, Comedy Central, and Spike TV. In 2010 she also launched Sweet, her very own swimwear line.

Our favorite Kayla Collins project is definitely 'Mandatory Physics' though. Check out an episode below with some more pics and be sure to follow her on Twitter.
