However, People magazine's source insists the Come and Get It singer is not back with Bieber, who she previously dated on-and-off for three years.
Gomez revealed in September that she had the transplant because of her lupus, a chronic inflammatory disease that occurs when the body's immune system attacks its own tissues and organs.
The 27-year-old singer and Selena, 25, recently ended their ten-month relationship, and a source close to the situation has suggested the Canadian star considered the brunette beauty to be secondary to his music career. He's allegedly texting her nonstop when they're apart. At first, the Weeknd was like "this is fine, what deviant undertakings can possible occur in the House of God", but apparently he's since rethought his stance.More news: Kerala Woman Hadiya's Case Not 'Love Jihad,' Says Activist Who Shot Videos

The duo attended church together and were photographed by TMZ grabbing breakfast at a café in Westlake Village, California, in late October.
And now Selena's family is anxious that she might be making a huge mistake by hanging out with Justin Bieber again.
"(She) always made an effort (to go to his concerts), (but) that played a part in them getting distant", the insider adds. Bella loved Abel and was friends with Selena so when they started dating it definitely hurt. Gomez is focusing on her health, a third source told Us Weekly.
"Bella isn't surprised that Abel and Selena split", a source said. It wasn't going to last. Bella isn't mean spirited, but she isn't exactly shedding a tear that they split either.
