Justin Bieber is reportedly using Selena Gomez's family to get his on- and off-again girlfriend back.

Bieber is seemingly trying to get Gomez's attention by approaching her family members first.

"Justin knows Selena's family is everything to her, so he's been trying to get to her through them," a source told Hollywood Life. "He's been sending lots of flowers to her grandmother in Texas, and he's even sent flowers and messages to her mom. ... It might not get her family to try to help them, but he's hoping it still gets Selena's attention."

Also, the Canadian pop star apparently feels confident that he and his lover can get back together eventually.

"He knows Selena believes they belong together, so in his mind, he's gonna get her back," the source said. "It's just a matter of how long she holds out. But to be honest, he loves that chase, that drama. It gets him fired up."

Meanwhile, according to Star magazine, Gomez's mother and former manager Mandy Teefey is reportedly worried about her daughter's recent decision to enlist her enemy Kendall's mother Kris Jenner as her manager.

"Mandy understands Selena's decision to upgrade her management. ... But she's worried about Kris turning Selena into a trashy Kardashian," an insider said. 

"On the rare occasion when Mandy does talk to her daughter, it's 'Kris says this' and 'Kris thinks that' -- Selena is completely under her spell. ... Kris is giving her advice on where to be seen, what to wear and what to share online, and Selena is lapping it up."

Moreover, the "Come & Get It" even shared a ride home from the airport after flying back from their Paris Fashion Week trip.

"Selena spoke to Kris about her passion for spreading awareness about bully prevention and her desire to make a difference," a source told Hollywood Life. "October is National Bullying Prevention Month. Kris told Selena that she would help her with her cause and thanked her for her efforts to raise awareness. Kris was really sweet to Selena and acted very motherly."
