Kaley Cuoco-Sweeting Says Her Husband Ryan 'Loves' Ex Johnny Galecki: 'I Got Lucky'

Playing an on-screen love interest with an off-screen ex is pretty common on TV – think The O.C.'s Adam Brody and Rachel Bilson, One Tree Hill's Chad Michael Murray and Sophia Bush or Gossip Girl's Penn Badgley and Blake Lively.

But Kaley Cuoco-Sweeting says there's no awkwardness between her and her Big Bang Theory costar/former boyfriend Johnny Galecki – or between him and her husband Ryan Sweeting.

"We dated like five years ago, so I think everyone's moved on," Cuoco-Sweeting, 29, said on Watch What Happens Live on Sunday night. "Johnny's actually one of my best friends. It's a situation that ended well, I understand sometimes it doesn't."

As for her tennis player hubby?

"Ryan loves him, Johnny loves him. It's been a long time, so it's great," she said. "I got lucky. It could have been horrible."

The actress and Sweeting, 28, tied the knot in a fire-and-ice-themed wedding on Dec. 31, 2013.

And when she forgot to thank her new spouse at the People's Choice Awards this year, Galecki, 40, swooped in for the save.

"Ryan, you are my heart," he joked.
