Selena Gomez Justin Bieber relationship may be over, but not in a song.

While Bieber proudly enjoys his single status, partying with models in Ibiza, look at what his ex is doing. Selena Gomez uploaded a video in Instagram singing a slower version of her song, "Who Says."

The song aimed to take shot at her ex-flame's effort to boast his single life all over online.

Gomez sang the lyrics from the song that rang true, according to Hollywood Life:

"I'm no beauty queen, I'm just beautiful me,"

Selena Gomez Justin Bieber fever heated up as Selena included a caption on her video that read:

"A little throw back during warm ups."

The singer bashed her ex for making her feel insecure with his recent model dating adventure.

Shanina Shaik, a Victoria's secret endorser was Bieber's latest flame. Fans have seen the cozy photo the "Boyfriend" singer posted of himself and the model. Bieber was also seen getting close to Playboy playmate Alyssa Arce right in his own yacht last July 31!

As a way to get revenge on Bieber, Selena has been showing off her curves recently. She was recently spotted wearing short wardrobe. Selena also presented her underbutt cleavage like she's never had, in years.

This is just the tip of the iceberg for the Selena Gomez Justin Bieber feud! Will the former couple ever get over what they had in the past, and move on? Is Selena the only one who's not moving on? Feel free to tell us what you think!
