Justin was her worst since he trashed her.
She says it in For The Record too. That along with K-Fed but only because she had children with K-Fed.

No she didn't, all she said about Justin was that she kept busy afterwards and while she was devastated she handled it a lot better than the one with kevin.

I remember her sister saying in court that Britney has never been the same after JT.

EDIT:
Here is all about it it was statements made from Britney's lawyer.

Bur JL wasn't at any of her court hearings.

I was wrong it was Britney's lawyers that said that.

She's still reeling from that breakup with Justin

This.

Well Justin showed his true colours after the two split which must have been hard for her, but obviously Kevin was much more to take - he was the father of her children. Not that anyone is expected a bunch of ****-hungry teenage queens to understand emotion like that

Oh really, I must have missed that part every single time I've watched it.

Of course Britney changed after the JT breakup. She learned many things. She was also young, people are bound to change and grow around that age.

And Justin still misses her too
