Kaley Cuoco-Sweeting wouldn't ''have her career'' without horseriding.

The 'Wedding Ringer' beauty insists her six horses are the ''biggest blessing'' in her life and credits the sport for making her ''centred'' as a person.

She said: ''I have six horses, and they have been the biggest blessing in my life.

''Horseback riding is why I'm so centred, especially in this business. I wouldn't have my career without it.''

To stay healthy, the 29-year-old actress - who is married to Ryan Sweeting - recently adopted a vegan and gluten-free diet and insists it has ''completely changed'' her.

She added: ''I'm not a vegan, nor do I have a gluten allergy, but it just feels better in my stomach. Everything, from the inside out, has completely changed for me.

''And now, when I look into the mirror and see the positive changes, I don't want to go back to what I was doing. Especially when my husband is like, 'You look amazing!'''

And Kaley has ditched a bad sweet habit she picked up over the years - of keeping treats in her beside drawer.

She told SHAPE magazine: ''The drawers next to the bed were filled with candy. Eventually, I realized it was mindless eating. I was just doing it because he was doing it, and it was adding hundreds of calories I didn't even think about.''
