Avril to Deryk -- See You L8ter Boi

It's official, Avril Lavigne and Deryck Whibley's marriage is over.

Avril just posted the following message on her blog:

"Deryck and I have been together for 6 and a half years. We have been friends since I was 17, started dating when I was 19, and married when I was 21.

I am grateful for our time together, and I am grateful and blessed for our remaining friendship. I admire Deryck and have a great amount of respect for him.

He is the most amazing person I know and I love him with all my heart. Deryck and I are separating and moving forward on a positive note.

Thank you to all my family, friends and fans for all your support
