Selena Gomez and boyfriend Zedd are back together following their rumored split after the "Behaving Badly" singer allagedly realized that her ex ,Justin Bieber, has not really changed at all. The former Disney star's past flame is also rumored to collaborate with the "Stay the Night" DJ.

The 22-year-old "Come & Get It" singer is now back to the German DJ's arms after reportedly realizing that the "Baby" hit maker "has not changed half as much as he claims to have," Celebrity Dirty Laundry report said.

After the "Boyfriend" singer's recent birthday, Selena Gomez realized that Justin Bieber did not really grow up. Accordingly, the "Baby" singer still  has the same negative attitude that the former Disney star has struggled to deal with in the past years, the report added.

Now, "The Heart Wants What It Wants" singer Selena Gomez is now back to boyfriend DJ Zedd who could not be happier about his reunion with the star.

However, the report added, "Zedd is completely aware of the fact that the only reason Selena Gomez is with him is because she couldn't be with Justin."

This has allegedly resulted to Zedd being a clingy and needy boyfriend.

The source added, "His insecurities are driving Selena away."

Meanwhile, reports are emerging that Selena Gomez's boyfriend Zedd will work with Justin Bieber's new album, Sugar Scape said.

"Things are good [between Justin and Zedd] right now. Zedd might even work on a track for Justin's album so the bad blood is over," the source from Hollywood Life said.

This came up amidst rumors that Justin Bieber is going crazy over Selena Gomez's new relationship with the "Spectrum" DJ.

In a separate report, the "Baby" hit maker is meanwhile hinting that he is not rushing on his new album.

An insider claimed, "He is working on new music but it's still a bit of time [until it is ready.] He is not going to rush an album just to rush an album."
