Over the years, Brad Pitt and his makeup artist, Jean Black, have formed an extraordinary bond. However, it is not just because of the time they have spent together, but due to the moment that the beauty guru had to put makeup on the 56-year-old actor's butt. In the an episode of the new HGTV show, Celebrity IOU, Angelina Jolie's ex-husband recalled the hilarious story between him and the makeup expert to hide his skin problems.

Jean Black had to put the foundation on Brad Pitt's behind because of his "bad tan lines" on the set of the 1994 movie Legends of the Fall. Black needed to even out Jennifer Aniston's ex's skin tone, so she was left with no choice but to see his backside and apply makeup on it.

"When it comes up, we can't really look each other in the eye," the Once Upon a Time in Hollywood actor said, via People. "She's family; we're like brother and sister. She's been that person I value so much in my life."

Brad Pitt is not the only one who talked about his close relationship with Jean Black. In 2017, she told GQ that the father-of-six is a "fantastic human being" after they have worked together for so many years.

They have been together since the Fight Club star's early years in the business, and a lot of things have happened since then. She saw the most significant things that life gave him, along with the most devastating ones that he had been through.

Celebrity IOU, which will premiere on April 13, give celebrities a chance to show their gratitude to people who help shape their lives or career by offering their house a complete makeover approved by HGTV. So to show his appreciation to his longtime makeup artist and friend of more than 28 years, Brad Pitt chose Jean Black to have her home renovated by the celebrity contractors themselves, Drew and Jonathan Scott.

According to Us Weekly, the Inglorious Basterds actor took advantage of the time when Jean Black had to leave her home for three weeks to do the renovation. Drew and Jonathan Scott managed to transform her guest house in Santa Monica, California, into a lavish suite within the given time.

To make sure that Jean Black would get the best renovation, Brad Pitt stayed on-site and watched the Property Brothers do their thing. He tried to help as much as he could but said that he would only "jump in" when he could and leave out all the rest to the "experts."
