Justin Timberlake is grateful to the fans who bought 968 thousand copies of The 20/20 Experience, ensuring his album's debut at number one on the Billboard 200 album chart.

On Wednesday, he tweeted to his followers, "Whoa... Speechless. Shocked. Numbers go up, numbers go down. I just hope this album makes your Summer...You already made mine #bestfansever."

Then, somewhat cryptically, he added, "I'm gonna find a way to show my appreciation to you ladies and gents this week...Stay tuned. #finderskeepers."

Justin didn't offer any hints, so keep monitoring his Twitter feed for updates on what's in store.
