It's safe to say that Kaley Cuoco just keeps getting hotter. On Wednesday, the actress hit the red carpet for the Alzheimer's Association's "A Night at Sardi's" benefit in Beverly Hills, and we couldn't ignore the fact that she looked smokin' hot. On top of turning up the heat in a supersexy cutout dress [1], Kaley gave us yet another peek at her enviable abs [2], leaving us all at a loss for words. Before making her way inside the Beverly Hilton Hotel, she met up with her ex-boyfriend [3] and The Big Bang Theory costar Johnny Galecki, as well as Laurie Burrows Grad, who chaired the event benefitting the Alzheimer's Association [4].

Kaley's latest appearance comes on the heels of a busy couple months for the star. After Kaley grabbed headlines for her night out with Sam Hunt [5], she made an appearance on The Ellen DeGeneres Show [6], and most recently, she opened up about her recent split from husband Ryan Sweeting [7] in Cosmopolitan's latest issue. Read on to see more of Kaley's sexy night out, and then watch her channel her inner Britney Spears [8] on Lip Sync Battle.
