Bill Clinton -- Hookers Schmookers -- I Love Posing With Pretty Girls

The two hookers who scored a photo with Bill Clinton over the weekend say the Prez still has an eye for pretty girls ... and he told them so.

Ava Adora told us on TMZ Live ... she and Barbie Girl made a beeline for Clinton at the event -- much to the chagrin of the Secret Service. They expressed their love, and he said, right back at ya.

Dennis Hof -- who owns Nevada's Bunny Ranch where the girls work -- scoffs at the charity's contention the girls were not allowed to be there and were unceremoniously thrown out. He says they had tickets and actually closed down the joint ... with a HUGE porn star.
