Her relationship with Justin has really affected her relationship with her mom, and it's been hard for her because she is super close with her mom.
Since the rumored reunion of the two, they have been under constant media scrutiny and it has apparently led the couple wanting to separate for the time being.
Another source added to People that their "break" has nothing to do with Gomez' mom, Mandy Teefey, who has made it clear she didn't approve of her 25-year-old daughter getting back together with her ex-boyfriend, who just turned 24.
Though the Wizards Of Waverly Place star's mom Mandy Teefy was initially blamed for the split, other sources claim the couple "have their own issues" and Selena's mom had nothing to do with her decision, according to People. "She wouldn't base her relationship off of what her mum thinks".
Bieber and Gomez began their romance as young teens in December 2010.
After Gomez received her kidney transplant due to her ongoing battle with Lupus, Bieber allegedly rushed to be by her side.
"Selena and Justin chose to take a break mainly because of Selena's mom and her disapproval of Justin", a source told the publication. "They're not hanging out together, but they've been communicating". "This time around, they're both in it for the long run, so they're committed to not sweating the small stuff, and to giving each other space when needed", another source revealed.
Still, Gomez and Bieber never publicly defined themselves as a couple again. It's said they're back in contact after an estrangement.
'They've been having disagreements, but it wouldn't be surprising if they're back together in a week, ' the source continued.
