Not everyone is a fan of Selena Gomez and Justin Bieber's rekindled romance.
A source tells ET that Gomez’s mom, Mandy Teefey, was recently hospitalized and continues to be unhappy about the reunion between Bieber and Gomez -- and the reasons go back years. TMZ was first to report the news of Teefey's hospitalization.
“She had a breakdown and checked herself into a hospital,” the source says. “The breakdown last week was likely the result of a culmination of stress of the holidays, the anniversary of her miscarriage -- which hit her very hard -- and the stress of Justin and Selena getting serious.”
"[Mandy] is not handling Justin and Selena’s reunion well,” the source continues, adding that Teefey is now in Dallas, Texas, to be close to family.
According to the source, unlike Bieber's mom, Pattie Mallette -- who appears to wholeheartedly approve of Gomez -- Teefey hasn't been a fan of her daughter's relationship with 23-year-old Bieber since the two superstars were together in 2014. The source claims Gomez chose Bieber over her family, and that Gomez and her family only reconciled after the breakup.
“Her family was there for her to pick up the pieces that Justin had left behind," the source claims. "They helped get her back on her feet and things were finally looking up for Selena."
As to why Teefey is so distraught over Bieber and 25-year-old Gomez's current reunion, our source notes that the last thing Teefey wants is for Bieber to "unravel" all of Gomez's progress after undergoing a kidney transplant over the summer.
"Selena has a second lease on life -- it would be a shame if she repeated the same mistakes this time around too," the source claims of Teefey's mindset.
Although, following Gomez's kidney transplant -- and after she split from The Weeknd -- the "Wolves" singer ended up reconciling with Bieber.
"Justin came back into her life. Emotions were high after the surgery, so it was the perfect opportunity for them to reunite,” the source explains. "Justin and Selena really bonded over their faith and feel like this is a brand new relationship -- even if other people don’t see it that way.”
According to our source, Gomez and Bieber's rekindled romance isn't ending anytime soon. The source says the two are even receiving private couples spiritual counseling to stay on track. On Saturday, the pair took a private jet to Seattle, where they enjoyed a date at The Sugar Factory.
“They are very serious," the source says of their current relationship. "They are in this for the long haul. They may be young, but don’t forget, both their parents married young and had children young, so this is normal to them, plus they’ve already accomplished so much career-wise. They’re at a point in their lives where marriage and kids are definitely on the table."
ET has reached out to Teefey for comment.
Last week, a source told ET that Bieber isn't taking his second chance with Gomez lightly.
"Justin wants to be a better man because he doesn't want to screw things up with Selena," the source said. "He knows he's lucky to have this second chance and he's not taking it for granted."
"Justin really messed with Selena the first time around and she was in a bad place because of it," the source also claimed. "Over the years she's worked on herself and is way stronger now, but they were all still worried at first that it would all unravel if things went south. Luckily, it seems things are going really well and he is back in some of her friends' good book."
Meanwhile, it's undoubtedly a difficult time for 41-year-old Teefey. On Monday, she paid tribute to the child she lost to miscarriage in 2011.
"Thank you to all the fans who honored our Scarlett yesterday," Teefey wrote in an emotional Instagram post. "Dec 17th will never be the same, but we decide to celebrate her by writing her letters on red balloons and releasing them."
