This was the most intelligent decision she could do in a long time. But the way she went about it by texting him its over was wrong too. That was completely immature and childish, but with a husband like K - Fed, it seems justifiable.
Personally, I think he was dragging any ounce of stardom she had down the toilet. Everywhere you looked he was in the tabloids whether out partying, drugs, or his ridiculous spending habits. Not to mention that awful "rapping" career he had going lol. And I saw on Entertainment tonight he did some guest appearances on WWE. He got publicity because of Britney, not because he was a quality star. I always kept reading about the bodyguard shopping with Britney or taking care of the baby.
K - Fed was a loser, I have no idea what she saw in him to begin with. He wasn't even remotely handsome, he hardly had any goals in mind other than partying.
I do hope Britney gets herself in gear. I would like to see an album from her, I actually miss some of her dance hits.
