Justin Bieber

One day after Selena Gomez posted a mysterious photo from the shower on Instagram, ex-boyfriend Justin Bieber shared one of his own -- and they're extremely similar.

Bieber's post sparked questions of whether he and the "Come and Get It" singer may be working together on a new music video.

Both stars were recently spotted together in a Snapchat video posted by Hillsong pastor Rich Wilkerson Jr., which showed a group of friends hearing another freestyle rap.

Gomez has recently been hinting at new things coming in terms of her career. On Instagram earlier this week, she wrote, "I am beyond excited to show you the next chapter, the TRUTH. I've been keeping so many secrets... I'm reborn in every moment so who knows what I'll become.. As long as I'm happy with me."
