They've been divorced for nearly 10 years, but Angelina Jolie still has a soft spot for ex-husband Billy Bob Thornton.

In Billy Bob's new book, The Billy Bob Tapes: A Cave Full of Ghosts, which Life & Style has obtained, Angelina pens the forward and says her former partner "has a big beautiful heart."

But that's not at all: "He has an unmatchable wit and can make you laugh until your face hurts," Angie writes.

The 36-year-old actress, who got engaged to partner of seven years Brad Pitt in April, gives even more details about Billy Bob's personality.

"To be with him is like being with a mad mathematician," she adds. "He is constantly counting and repeating."

Along with talking about the things the 56-year-old actor loves and dislikes, Angie admits the world, and she herself, would not be the same without him around.

"Some people walk through life able to quiet the voices in their heads. He can't. And I, and everyone else who knows him well, we love him for it," she says, ending with, "I know one thing: The world would certainly be a hell of a lot more dull if that man weren't in it."

Billy recently opened up about his marriage to Angie, calling the failure of their relationship his fault.

"I blew it because I didn't think I was good enough for her," he said. "She has one way she wanted to live her life and I had another way to live mine, and I was just too insecure."

Billy Bob Thornton and Angie Jolie, who co-starred in the 1999 film Pushing Tin, married in 2000 and were divorced in 2003.

Adele has millions of fans, but she's a fan herself...of Spanx!

After the singer admitted to wearing four pairs of the slimming undergarment during her Grammy performance in February, Spanx founder Sara Blakely tells Life & Style that she's excited to hear the news - the 24-year-old is the first celebrity she's heard of to wear that many at one time!

"Spanx used to be the celebrity slimming secret and has become the red-carpet staple they love to talk about," Sara tells Life & Style. "We've heard about wearing double and triple pairs of Spanx, but I'm thrilled to hear that Adele is our first quadruple. Now that's commitment!"

On May 11, Adele admitted to wearing multiple pairs underneath her Giorgio Armani gown during one of the most memorable nights of her life.

"I had like three or four pairs of Spanx on that night," she said. "I loved it. I actually had another dress made for the Grammys, but I passed out in it. I had a corset, and I was like, 'I can't wear that,' so I ended up wearing this at short notice."

But the star reveals she certainly couldn't wear all the Spanx during her powerful rendition of "Someone Like You."

"I took a couple pairs off when I sang at the Grammys," she said.
