"The Big Bang Theory" actress Kaley Cuoco recently sparked rumours of being in a relationship by posting online a picture of her indulging in public display of affection with a mystery man, who was later identified as Karl Cook.

The photo she shared on her Instagram page showed the guy licking her forehead. Cuoco added an emoji of an arrow going through a heart as a caption, and this had many of her Instagram followers wondering if she was in a relationship — her first since splitting from Ryan Sweeting late last year. This was Cuoco's second picture with Cook. Another picture of the couple had Cuoco with her arms wrapped around the 25-year-old.

It would make sense if Cuoco is dating Cook as they both love horses. Cook is an equestrian, and according to ETOnline, he took home the blue ribbon in the $25,000 SmartPak Grand Prix earlier this month. Cuoco is also an avid rider, and last month the Humane Society gave the 30-year-old the title of 2015's Horsewoman of the Year.

Cuoco is yet to confirm these dating rumours, but the actress had said on the Ellen Degeneres Show last month she was in a much better place since her split from husband Sweeting in September 2015. She also expressed hope that 2016 would be better than the previous year, and added things were looking much better already.

However, in an interview with Cosmopolitan earlier this month, Cuoco said she would need some more time to fall in love again.

"[What happened] changes the way I look at marriage, and that makes me sad," Cuoco told the magazine. "It does not change the way that I look at love. I cannot wait to be in love again. I don't feel like I am ready yet...which is so different for me. I dive into everything."

Cuoco's previous boyfriends include "Batman V Superman: Dawn of Justice" actor Henry Cavill and "The Big Bang Theory" co-star Johnny Galecki.
