Britney Spears bedded her childhood sweetheart "like an animal", then wrecked his life with a 55-hour marriage that stunned the world.
Now, in a world exclusive interview, husband Jason Alexander details every moment of the sex, the proposal, their Vegas wedding and his humiliation as furious family and lawyers prised them apart.
Jason revealed that Britney proposed to him as she lay naked in his arms. And she was so excited when he said "Yes", she rushed him down the aisle without stopping to put her knickers on.
"We knew what was going to happen," he said. "Britney started stripping off her clothes as she walked into the suite. Then we started kissing.
"She got down to just her black thong and a see-through lace bra. I've never seen a woman look more stunning.
"I wanted to make love to her and she wasn't shy in showing what she wanted. We started off in the bedroom kissing. She was good at that—she was good at everything. She was an animal in bed.
"We were both hot so I led her into the bathroom. We stripped off competely and got into the shower and Britney performed oral sex on me as the water ran down over both of us.
"We made love in her bed, her shower and her bath," said Jason, 22. "She asked me to marry her but when her lawyers demanded I end our marriage she didn't stop them—and it caused chaos in my life."
