George Clooney and Pamela Anderson have become Hollywood's most unlikely couple after the pair was spotted frolicking together on a romantic, fun dinner date. The Oscar winner booked a private room at Sherman Oaks, California, restaurant the Valley Inn, and entertained the actress there on January, according to reports.

And since that evening, which ended with Anderson sitting on her date's lap, the odd couple has been spotted out and about, enjoying dog walks together. A pal says, "George and Pam have been determined to keep this one quiet."

Bachelor Clooney has dated a string of beauties; Anderson split from husband Kid Rock last year after a brief three month marriage. She was formerly married to rocker Tommy Lee.
