Diane Kruger flaunted her amazing bikini body in Cabo San Lucas Saturday.

Wearing a mismatched top and bottom -- a itsy bitsy triangle bottom -- Diane was poolside with boyfriend Joshua Jackson.

Kruger and her Fringe star beau split their time between Vancouver and Paris and obviously sought out some southern sunshine for the Thanksgiving weekend.

The acting couple have been together five years, and that ring Jackson is wearing?  It's not a wedding band. When asked about it in a recent interview, he explained he and Kruger aren't married but they are "committed."
