Kaley Cuoco ties the knot

Kaley Cuoco ties the knot with .... - The Big Bang Theory

Kaley Cuoco ties the knot with real-life ex-boyfriend Johnny Galecki in ‘The Big Bang Theory’ season premiere.

The former real-life couple were cast in a familiar light Monday during the season 10 opener of “The Big Bang Theory,” where characters Penny and Leonard, played by the ex-duo, shared a nostalgic kiss and wedding vows.

The pair were in a relationship for “almost two years” according to Cuoco. Cuoco said they tried to keep quiet about their romance because they were both cautious about how fans might perceive their off-camera romance. She told CBS Watch! that the "relationship was such a huge part of her life."

Galecki told the magazine in 2013 that he considered Cuoco a "dear friend," saying that he doesn’t think of her as an ex, but as a huge “part of his life.”
