He's really laying it all out there!

Justin Timberlake looks back on his unbelievable life in his new book Hindsight & All The Things I Can't See In Front Of Me, and he goes into detail about his split from Britney Spears and how he found his happily ever after with wife Jessica Biel.

JT seemingly confirmed what everybody already knew, that Brit Brit cheated on him and caused their breakup, which inspired him to write his hit "Cry Me a River" just two hours after the relationship fizzled.

"I've been scorned. I've been pissed off. The feelings I had were so strong I had to write it. I translated my feelings into a form where people could listen and hopefully relate to it. People heard me and they understood it because we’ve all been there," he explained.

The singer also revealed that he met now-wife Jessica Biel at a private party in 2007, but failed to get her number and they went their separate ways until she came to see him at his San Diego concert months later. The rest is history, as they say!

"Jess changed me. She changed my life. We've had a lot of unforgettable times. She's been a huge influence on my life, and I have such admiration for her, especially seeing her as a mother now. I've watched my wife change. I've watched her body change. It's a temple. It should be worshiped. It should be marveled at. I'm fascinated by her. She's everything, man. I wake up and roll over and look at her, and I'm inspired," he gushed. Aww!

Things got even sweeter when they welcomed their son Silas together.

"Having a child has been the pinnacle of my life. I had such intense feelings – nothing that I've ever experienced can compare to it. The things I have learned from being a father have been profound. I'm just coming into my own and I'm at an interesting crossroads in my life. It's terrifying...invigorating...more meaningful than anything I've ever been a part of. Kids teach you more than you teach them," he admitted.

Britney really threw away a good man!
