Selena Gomez and Justin Bieber, better known as Jelena, have already jumped right back into their old relationship. Fresh off her breakup from The Weeknd, Gomez began hanging out with her former flame again, making us all wonder exactly what was going on. 

But recent sightings and confirmation from a source bring us back to 2011 when the two youngsters were hopelessly in love.

Bieber was reportedly the one to pursue Gomez and win her over back into a relationship.

According to TMZ, sources close to both Selena and Justin confirmed that he was the one putting in the work to reignite the spark between the two.

Bieber's move was not random, of course. He reportedly responded to Selena's medical issues in recent months.

Gomez has been open about her kidney transplant with best friend Francia Raisa, which left her in pain and close to death as a result of her Lupus diagnosis.

According to the source, Bieber "didn't know how much she still meant to him until he realized she could die ... and that made all the difference."

And though she certainly had to be "won over", it ultimately led to the couple reuniting on more than one occasion over the past week:

Welcome back, Jelena.

We never knew how much we missed you.
