Kaley Cuoco loves yoga - because it means she can drink wine.
The 'Big Bang Theory' actress credits her regular sessions of meditative exercise for her enviable figure and joked they mean she can consume whatever she wants without worrying about her weight.
She said: "Yoga is the secret. Yoga is the reason that I have been [looking great]. It has done everything, mentally and physically. I love it...
"I only go to yoga to drink wine, so I'm good. I just throw the calories right back in."
And despite looking glamorous on the red carpet, Kaley never feels more attractive than after her daily yoga session.
Asked when she feels sexiest, she said: "In yoga pants, at home with the dogs, drinking my wine after yoga."
The 30-year-old star is amazed 'The Big Bang Theory' - which premiered in 2007 - is celebrating its 200th episode and couldn't be happier to be a part of the show.
She told 'Entertainment Tonight': "This is unbelievable. To still be number one, it makes no sense. [We have] amazing writers, an amazing cast and crew of people.
"This is a dream come true. You don't ever think you are ever going to get to a point like this, and then when you are here, it is all about gratefulness, so I am thrilled to be here."
