Does "The Big Bang Theory" star, Johnny Galecki still love co-star, Kaley Cuoco?

According to US Weekly, the actor, 38, who once dated the blonde starlet, opened up about his secret relationship recently amid the cast filming the show's 7th season.

Three years after Cuoco revealed the pair had a two-year romance, Jim Parsons' and Mayim Bialik's male co-star just now shared his feelings on having dated the now-newly engaged actress. Galecki said the two are still on great terms, obviously having to still work together on their hit CBS comedy.

"We're dear friends, still," said Galecki to the December issue of CBS Watch! magazine. "Kaley's not just an ex, she's a part of my life." 

As to why it took the former "Roseanne" star so much time to open up, he had an answer for that, too.

"I just don't like to speak about it," explained Galecki. "And not because I'm trying to be enigmatic; I just worry that it will conflict with people's acceptance of Leonard and Penny [the stars' characters on their show.] I get the curiosity, but I don't want to distract from the story."

Galecki and Cuoco have starred in the nerd-themed series together since 2007. In September 2010, Cuoco talked about their now-defunct relationship for the first time with CBS Watch! 

"We dated for almost two years," shared Cuoco. "It was such a huge part of my life and no one knew about it. This is the first time I've ever talked about it, ever. It was a wonderful relationship, but we never spoke a word about it and never went anywhere together." 

Cuoco continued, "[We were] so protective of ourselves and the show, and we didn't want anything to ruin that."

Unfortunately, Cuoco also admitted that having kept quiet about their romance eventually took a toll, leading to their split. 

Now, the blonde actress is getting ready to walk down the aisle with tennis player, Ryan Sweeting. And Galecki is dating girlfriend, Kelli Garner, former star of the canceled ABC series, "Pan Am."
