However, it seems that the problems between Selena and her mother have a much longer history.
A week after Selena Gomez' mum, Mandy Teefey, was hospitalised following an alleged heated argument over Justin Bieber, a family source has debunked the claims that their family issues were caused by the Canadian singer.
The ladies all went to the bridal salon followed by a fun dinner out with drinks and celebrations for the bride-to-be and it looked like they all had a blast.
The singer is, however, reportedly adamant to give another chance to Bieber by renewing their love this New Year and wants to welcome 2018 with a kiss from her rumoured beau.

"But still, they've had a really complicated relationship and have gone through a lot of ups and downs".
"Mandy and Selena's stepdad [Brian Teefey] really did everything they could for Selena so when she fired her it took a toll on Mandy emotionally and professionally", the source added and explained that Selena's mother "lost her clout as a manager" after she was sacked by her songstress daughter.
While Selena enjoyed her night out with her cousin and friends, the award-winning singer also took time to take pictures with fans at the bar. The two walked on the red carpet during the premiere of "13 Reasons Why" in March.
Back in November it became clear that Selena and Justin became a couple once again when paparazzi spotted them together on numerous occasions.
It seems that after Selena fired her mother as her manager, this caused emotional and professional issues for her mom.
