Meanwhile, the 30-year-old actress previously claimed she wouldn't "have her career" without horseriding.

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."
And Kaley doesn't think her relationship with Karl Cook would be so strong if they didn't share a love for horses.
She explained: "When you share something so special, some sort of connection - for us, it's horses, but anything two people share - you have that common goal and you know that you want the same things in life, day to day, and in the future.
"It just sets you on a better path. Having a lot in common is really important and we definitely have a lot in common. I think that that's what makes us so strong and really happy."
