Fun and feisty are appropriate words to describe some of the female stars in the best comedy series still running today. Acting in comedy shows requires brilliant timing and an air of quirky pizzaz. The first bring in the fun, the second gives the feisty flavor. All the rest becomes mere "bonus."

Here are are five of the hottest female stars in U.S. comedy series today.

5. Hannah Simone - She plays Cece in the Fox comedy, "New Girl." Her childhood best friend has just moved in to a loft with three guys as roommates. She threatens everyone that if anything bad happens to her best friend, she would hunt them down. Midway through the first season, she falls in-love with one of the guys. Her booty-call-turned-boyfriend breaks up with her after watching her in a raunchy photoshoot with one of the male models.

4. Kaley Cuoco - She plays Penny in the hit CBS series "The Big Bang Theory." Charming, lovely and sexy, Penny won the heart of her new theoretical physicist neighbor at first sight. Not long after that, Penny has become her neighbor's spider killer. She is only her guy friends' only chance at winning paintball and bowling games. One of the best "Big Bang" episodes are those with the Penny-Sheldon repartee. Cuoco and Jim Parsons make a great comedic team on TV.

3. Sofia Vergara - Playing Gloria Pritchett in ABC's "Modern Family" has raised Sofia Vergara's celebrity status to new heights. She is now one of the highest-earning female TV stars, with Emmy nominations under her belt. The mockumentary directing style of "Modern Family" would normally frame her breasts for a playful tone, but it's never distateful. Besides, any lewd thought can be brushed off by the idea that her character is a Colombian gun expert who can shoot a person with her eyes closed.

2. Cobie Smulders - She will always be "How I Met Your Mother's" Robin Scherbatsky. This is what fans' memes said on Tumblr after she starred in the blockbuster hit "The Avengers." Smulders has definitely made a mark in the hit CBS series as a struggling news anchor and love interest of the New York city womanizer, Barney Stinson. Robin Scherbastsky has said this famous line at the Season 8 premiere when she described her new boyfriend: "I don't want to be crude, but I can spend all day licking his abs."

1. Kat Dennings - She has been seen in the HBO dramedy series "Sex and the City." She also starred in "The 40-Year-Old Virgin" and "Thor." But when Dennings landed a role in the CBS show "2 Broke Girls," it became clear she is no ordinary actress. As struggling waitress Max, Dennings has been known to spit out acerbic punchlines that could only come from a jaded New Yorker. The fact that Dennings can look effortlessly sexy in her voluptuous form, many fans of "Fifty Shades of Grey" are hoping to see her in the film adaptation of the E.L. James trilogy.
