Kaley Cuoco has perfected that post-breakup bod.

Since splitting from her husband Ryan Sweeting in September, the 29-year-old actress has been working out -- and it's paid off!

Kaley displayed her impressive results at the Fallout 4 video game launch party in Los Angeles on Nov. 5.

"The Big Bang Theory" actress showed off her toned legs and trim arms in short black shorts, a white halter top and black patent leather strappy heels.

She completed her look with a Jimmy Choo mirrored clutch.

Nice work, Kaley!
