Kaley Cuoco recently found love with equestrian Karl Cook, but he is not the first guy to ride straight into her heart. The actress has been attached to a number of actors over the years, including her "The Big Bang Theory" co-star Johnny Galecki. This is why recent reports say that Cook is acting indifferent towards the on-screen relationship of his beau and Galecki.

According to one report, Cuoco could be cheating on Cook and may have decided to get back together with her ex-boyfriend Galecki.

To recall, real life exes Cuoco and Galecki threw wedding ceremony on the season opener of "The Big Bang Theory". Both played Penny and Leonard, respectively, on the CBS hit drama series.

The pair dated for almost two years off-sccreen and Cuoco, who claims they dated between 2008 and 2009 revealed details of their secret relationship.

"It was a wonderful relationship, but we never spoke a word about it and never went anywhere together," she said during an interview.

"Everyone was always asking, and we deny-deny-denied. And I'm like, "Why am I denying this person that I love?" the actress further added.

However, on her recent interview with Cosmopolitan interview, she made clear that they were just good as friends now.

"Johnny and I are very close now, but the worst part about that is I don't want stories like that, especially during this divorce, to hurt my ex. We have nods with each other. Johnny and I do this thing like a nod that says, 'I got you. I get it," the 30-year-old actress shared.

Moreover, the actress and her new love Karl Cook recent made their relationship red carpet official when they attended the Longines Masters Los Angeles Gala in Long Beach, CA, on Thursday debunking jealous and breakup rumors. The couple showed sweet PDA as they walked the carpet holding hands together.

"The Big Bang Theory" actress Kaley Cuoco, who was Johnny Galecki's ex, first linked to Karl Cook in March, just six month after the actress divorced tennis pro Ryan Sweeting.
