Amber Heard feels ''normal'' riding her horse.

The 'Rum Diary' actress - who is engaged to Johnny Depp loves hanging out with her beloved pet Arrow when things in her life are getting ''crazy'' and says she instantly relaxed when spending time with her equine pal.

She said: ''Just standing here makes my blood pressure go down. When I'm in L.A., I come ride her five times a week. No matter how crazy things get, Arrow will immediately get me back to normal.''

The 28-year-old beauty used to relax by driving her beloved Mustang, but got rid of the vehicle as it was so recognisable to photographers.

She told W magazine: ''I do miss driving my Mustang. I built it from scratch, and I love that car. But the photographers all know the Mustang, and I hate being hassled. So it's stuck in the garage.''

Amber is very close to her father, but chose to ''rebel'' by resisting his attempts to get her interested in sports.

She said: ''He taught me a lot about animals, about cars, and about resilience. That's what happens when your father doesn't have a son. I drew the line at learning about football. I had to rebel somehow.''
