Leading lady Kaley Cuoco-Sweeting was the belle of the ball at Tuesday night’s world premiere of ‘The Wedding Ringer’ in Hollywood.

The jubilant actress who married her tennis pro hubby in 2013, shined as bright as her diamond ring from head to toe.

The movie about a shy young groom who turns to a best-man-for-hire to help him out so he can impress his in-laws stars funny duo Josh Gad and Kevin Hart.
