Salma Hayek may already be 48, but she looks a lot younger than that. When she walked the red carpet for her new film, "The Prophet," adapted from Kahlik Gibran's novel, she revealed to People Magazine her secret as to how she kept looking so young.

"Right now I am doing something that I'm really loving. It is called bone broth! It's sort of disgusting. You take a bunch of bones from a cow and you slow cook them for many, many hours." She also said that she adds in a tablespoon of apple cider to the broth, which she drinks everyday.

How does this help? She shared, "It's full of gelatin and fat and has bone marrow and I think it is very good to keep yourself young. If you do the right fat, I think that is the key." She added, "It helps to restructure the tissues for your skin, you hair and your nails. It's full of collegian [sic]."

She also said that the broth helped her avoid botox, which she said she's afraid of, despite its wide use in Hollywood.

Hayek is still very comfortable in her skin at 48, which she proved by going fully naked in the new film, "Some Kind of Beautiful" with Jessica Alba. According to Gossip Cop, the basic premise of "Some Kind of Wonderful" is that Pierce Brosnan, who plays a professor role in the movie, impregnates his student (Alba) but they split and he ends up falling for her older sister (Hayek).

The sneak preview showed Hayek enjoying a bit of an afternoon delight with her sister's husband. Unfortunately, their afternoon was interrupted when Alba's character came home unexpectedly while they were doing the nasty. So clad in a pillow to cover her lady parts, she scrambles out of the house with her rear on display.

But it doesn't stop there, because the same rear was also shown leaping into a pool, a sight that shocked Alba's character.

Hayek is definitely living it up. Just before the clip for "Some Kind of Beautiful" was released, the actress also had a topless cover shoot for Allure Magazine, a decision that she was more than happy to make. After the Allure photo was released, Hayek told E! News, "It's important to be free...and at my age it's exciting to still be able to take a photograph like that."
