Rosie Huntington-Whiteley says sleep is the key to looking good.
The stunning model-and-actress - who is dating actor Jason Statham - insists her beauty regime is quite simple and always tries to take good care of herself.
She said: "Water, sleep, exercise, organic food and regular facials. I go to the gym, do a lot of cardio and keep strong, which is really important to me."
While she is naturally beautiful, Rosie has previously revealed she uses chicken fillets to give her breasts a boost.
The Victoria's Secret model admitted she needs help in the boob department as she wants an ample cleavage when wearing certain outfits.
She said: "I'm not a fan of that whole push-up look in the day, but, of course, you do need a lift with a sexy dress.
"Do what you've got to do girls - shove them in there. I've been known to have three in at a time for shoots - plus padding."
