CBS's hugely popular sitcom "The Big Bang Theory" Season 7 is having a great run and it has managed to hold on to its high viewership. In the seventh season, Penny (Kaley Cuoco) and Leonard's (Johnny Galecki) relationship is at a stable phase after going through the hiccups of an on and off relationship status.

In real life, Kaley Cuoco and Johnny Galecki were in a secret relationship for nearly two years. They broke-up three years ago. And, for the first time, Galecki recently opened-up about his relationship with Cuoco. In an interview with CBS Watch! Magazine, he said that they're still "dear friends."

The actor also considers Cuoco not just his ex but a "part of my life." Galecki said: "I just don't like to speak about it. And not because I'm trying to be enigmatic; I just worry that it will conflict with people's acceptance of Leonard and Penny. I get the curiosity, but I don't want to distract from the story."

In 2010, Cuoco had talked about her secret relationship with Galecki. At the time, the actress had said that the relationship was a "huge part of her life."

"It was a wonderful relationship but we never spoke a word about it and never went anywhere together. We were so protective of ourselves and the show and didn't want anything to ruin that," Cuoco had said.

Both Cuoco and Galecki have moved on and are with different partners. Cuoco got engaged to Ryan Sweeting in September after dating him for four months. The media is abuzz with news that Cuoco might be pregnant.

Citing her friends, Blind Gossip reported that the actress is "round the twelve-week mark." According to the report, Cuoco is likely to make an announcement before the end of 2013. The report also said that the actress will "spend the next few weeks wearing loose-fitting clothing and hoping that you don't notice (just like Kerry Washington)."

Reacting to the pregnancy rumours, Cuoco tweeted on November 09, 2013 that she is not pregnant. "I would like to make something very clear to anyone who cares. IAM NOT EFFING PREGNANT. Do with that what you will."

Deadline.com reports that Jim Parsons, Sheldon, of "The Big Bang Theory," is negotiating to star in "Visions" along with Isla Fisher and Ellen Barkin. It is a Kevin Greutert directed thriller, which Blumhouse International is selling at AFM.
