Actress Kaley Cuoco, star of the hit series, The Big Bang Theory, is well known for her role as Penny, the crushworthy "girl next door" who eventually becomes the conquest of underdog Leonard Hofstadter.

But in Hollywood, she's also known for her ever-increasing number of short-lived relationships.

Now, since Kaley Cuoco has recently moved on from a divorce, we're expecting her to return to her serial dating ways very soon. But who were her past conquests and just how short were her relationships?

Kaley Cuoco and Jaron Lowenstein

In 2006, Kaley Cuoco was frequently seen around posing cheek to cheek with the chiseled jaw of singer Jaron Lowenstein, former member of the musical pop duo Evan and Jaron.

Lowenstein reportedly had plans to cast Cuoco in his single, "Pray for You," but he ended up having actress Jaime Pressley take the role instead.

Kaley Cuoco was just 19 when she began dating Lowenstein, who was 30 at the time. Although the two were photographed together quite frequently, they soon parted ways.

Kaley Cuoco and Josh Henderson

While Kaley Cuoco and Josh Henderson had initially met when they filmed 8 Simple Rules together in 2002, they actually began dating five years later, in 2007.

Cuoco and Henderson were photographed together leaving restaurants on date nights, but the relationship didn't last long enough to make formal appearances together.

Kaley Cuoco and Al Santos?

Also in 2007, Al Santos came into the picture.

Santos was an actor who shared the screen with Kaley Cuoco in the film, "Killer Movie." While there were many reports that the two were rumored to be dating, the romance was never confirmed by Cuoco.

Kaley Cuoco and Johnny Galecki

Hmm... we're starting to sense a pattern here. Starting in 2008, Kaley Cuoco had a secret relationship with her "The Big Bang Theory" co-star, Johnny Galecki. The relationship lasted for a period of about 2 years.

Around the time that their characters started dating, Cuoco and Galecki became involved in real life. However, the relationship remained strictly under wraps, and the couple were never seen together in public.

According to Today, the couple kept the relationship secret for professional reasons, citing a wish to protect the relationship of Penny and Leonard as the reason why they never revealed their romance (we don't understand that either).

While the gossip mill went into overdrive about the possibility of the couple reuniting shortly after Cuoco's most recent break up, both Galecki and Kaley Cuoco dashed fans' hopes and made it clear that they would not.

Kaley Cuoco and Josh Resnik

By 2011, Cuoco had amplified the pace of her relationships. In a brief period of time, she went from dating band manager and addiction specialist (yes, you heard that right) Josh Resnik to being engaged to him.

Though the couple did confirm their engagement, within six months the engagement had been called off. A wedding date was never announced.

Kaley Cuoco and Bret Bollinger

Beginning in 2012, as Kaley Cuoco gained a higher and higher profile, her dates also began to be more scrutinized. Cuoco was spotted with Bret Bollinger, bassist and lead singer for the band Pepper, at a Lakers game.

The two were also seen holding hands at the airport and kicking back cocktails.

The relationship was short lived, and pretty soon, she was on to the next guy.

Kaley Cuoco and Henry Cavill

Next came movie star Henry Cavill. According to Eonline, Cuoco's 2013 relationship with Cavill was also short-lived, lasting all of 10 days.

Cuoco said of the relationship that dating Cavill changed her life because she'd never been so photographed in her day to day life by the paparazzi as she was with Cavill.

Kaley Cuoco and Ryan Sweeting

Kaley Cuoco didn't waste time moving on after Cavill. She met tennis player Ryan Sweeting, about a month after the breakup.

And it wasn't long before the relationship went into high gear, either. Sweeting proposed to Cuoco about a month after they initially met.

The couple dated for 3 months and remained married for a total of 21 months. Cuoco even briefly changed her named to Sweeting.

Nevertheleess, Cuoco and Sweeting announced their divorce in 2015. According to coverage of their divorce by the Daily Mail, their divorce may have been fueled by Sweeting's rumored drug use, although there is no evidence of this.

Whew...There you have it, folks. Nearly a dozen of Cuoco's latest relationships. When will the next one start? Is there one already going on? We'll probably find out soon.
