Kaley Cuoco is getting ready to tie the knot.
The actress, 25, is engaged to marry Josh 'Lazie' Resnik, her rep tells PEOPLE exclusively.
"The surprise proposal took place during a quiet date night at home," the rep says. "The couple are very happy and excited to begin planning their wedding."
Cuoco and Resnik, who works as an addiction specialist, have yet to set a wedding date.
This isn't the first time the actress, who stars on the award-winning sitcom The Big Bang Theory
, has announced an engagement.
On the red carpet at the Golden Globes back in January, she joked about getting married
and sported a sparkler on her wedding finger.
But Cuoco quickly clarified: "I'd like you to know who I'm engaged to – Chopard, the jewelry designer." She then revealed she'd worn the borrowed ring on that particular finger because it fit perfectly.
