When you date people old enough to be your father, they know a thing or two!

Ashley Olsen and her financier boyfriend Richard Sachs hit the town in St. Barths last night, and when they were ready to head home, the 58-year-old pulled a chivalrous move and held the car door open for his 30-year-old lady love. We have to admit that at first this relationship looks a tad creepy, but we can kinda see what attracts them to each other now.

The designer and her twin sis Mary-Kate have always had a thing for older men, and MK is now married to 47-year-old Olivier Sarkozy.

Ash and Rich first made waves as a couple when they were spotted making out on the sidelines of a Knicks game in November. We wonder if this guy could be The One?
