Kaley Cuoco Save a Horse Ride a Jedi

Kaley Cuoco just drained the asthma inhalers of science fiction geeks across the galaxy ... by dressing up as a sexy Luke Skywalker.

The "Big Bang Theory" star was at the Longines Masters of Los Angeles -- a horse jumping event -- where she brought a whole Star Wars team to a charity costume part of the program, and even had a lightsaber duel with Darth Vader.

As we previously reported ... Cuoco added a new horse to her stable after it was revealed she filed for divorce from Ryan Sweeting.

One thing's for sure ... if Luke was actually that attractive, Han Solo may have had second thoughts about Princess Leia.
