Amy Winehouse states to Perez Hilton that she didn't get into a fight with her husband, that he saved her life. The two texted back and forth with her stating that:

“Blake is the best man in the world. We would never ever harm each other."
"I was cutting myself after he found me in our room about to do drugs with a call girl and rightly said I wasn’t good enough for him. I lost it and he saved my life.”

We don't know what's going on in her marriage or if what she states is true, but what we do know is that she needs serious help. Hopefully she gets it soon.
