There is not a day that goes by that this star is not working out.

But all that sweat equity has certainly led to some serious dividends as Kaley Cuoco was on fire on Wednesday night.

The 30-year-old sizzled at the 24th and Final A Night at Sardi's To Benefit the Alzheimer's Association in Los Angeles, California, first on the carpet and then on the stage.

While the actress has been slipping a little when it comes to red carpet style of late, the Big Bang Theory star turned things around at the event.

Kaley sizzled as she walked the carpet in a slinky sequined red dress which made sure to show off plenty of skin.

The floor length gown featured a plunging neckline from which the actress showed off her cleavage.

The dress then cut away providing the perfect showcase for her defined abs and slender waistline.

All that jazz: Getting in touch with her inner burlesque dancer, the actress took to the stage in just a pair of hot pants and an ab flaunting red crop top

The star skipped in wearing any jewellery leaving the dazzling up to her sequinned dress and carried a simple black clutch.
