Kim Kardashian's father Bruce Jenner has unveiled his new and improved face to the world.

Daughter Kim revealed that the 1976 Olympic decathlon gold medalist had given himself an early birthday present in the form of a face-lift, after an earlier session under the knife went disastrously wrong.

“He corrected work that was done 25 years ago that he wasn’t happy with,” Kim told Life & Style.

"We love the results! He looks 10 years younger. You can hardly tell he had anything done.”

While television viewers won't get to see Bruce's new face until the May 17 episode of Keeping Up With the Kardashians, Life & Style have obtained the exclusive sneak peek above.
