From the sounds of it, the timeline worked out without drama, too.
Gomez and the Weeknd amicably ended their ten-month relationship several weeks ago, so Gomez was single and ready to mingle when she brought Bieber back into her life last month.
However, a TMZ source said when Gomez underwent her successful kidney transplant surgery this year, Bieber realized how precious she was to him, so when they reunited in October, he followed his heart and persuaded her to date him one more time.
Although the reports of a rekindled romance sound convincing, some people say Justin Bieber and Selena Gomez decided to get back together because it could help their respective careers.
Of course, these moments add to the previous time when they reunited at Gomez's house for the initial reunion.
