Selena Gomez used her performance at the third annual Acoustic Charity Concert for UNICEF on Jan. 19 to sing revenge songs to Justin Bieber. Her performance of Justin Timberlake’s “Cry Me A River” spoke volumes about how she feels about Justin, and now it looks like he’s taking a page out of her book, by using music to express how he really feels. On Jan. 21, he retweeted a message, where he promised that his new album Believe will show us “how he feels.” Selena should be worried!

On Jan. 21, Justin retweeted this message from @JustinSoSwaggy: “Nervous but excited to here what justin has to say. We finally get to hear his side of the story and how he feels. #8days #proud :)” How pointed! Justin is clearly taking a jab at Selena. As HollywoodLife.com previously reported that Justin tweeted about his new songs being “honest”, and he said the album would address his and Selena’s break up.

He tweeted “Excited for #20Days from now when my acoustic album will let u know how I feel about what is going on in my life instead of rumors guessing. Put it in the music. Guess all u want I speak for myself. #20Days.” on Jan. 9.
