SURPRISE?

If you've been following Avril's Twitter profile, she has said that she has a a surprise, a thank you to us fans! We have been wracking our brains trying to figure it out, what do you think it is? Some good guesses include a 10 year anniversary edition of Let Go, Goodbye as the next single, Push as the next single, Hello being released, 5th album news, or info on possibly being a new judge on the X Factor USA

Avril's tweets:

Feb 25: "Guess what little black stars... I have a surprise for you.....!"

Feb 28: "Hint ..for my surprise..what is the title of my favorite song off of "Goodbye Lullaby" ?????"
Feb 28: "Guess what I'm doing right now??!"

Feb 28: "Bro'ing out with Chad Kroeger in the studio http://t.co/apQTm8rp"
Mar 1: "Wait for it......"

Mark Liddell, one of Avril's good friends and photographer extraordinaire (he has shot LOTS of Avril's best photo shoots - Maxim, Goodbye Lullaby, The Best Damn Thing, and Prestige, to name a few) has updated his Facebook recently with this cryptic message:
"Working on a very special and private project with one of my favorite clients. Cant say a word yet...but dam..people are going to FREAK the s*** out!!!! ..like nothing you've ever seen before!!!!!....." and also "it's going to be a big week for a lot of fans this week!!"... so the surprise has something to do with him and a photo shoot perhaps???
