Selena Gomez is reportedly 'on the edge' of exploding.
The 21-year-old Come & Get It singer stopped following everyone on her Instagram account in recent days, and Keeping Up with the Kardashians sisters Kendall and Kylie Jenner were the first to be removed.
It is claimed her ex-boyfriend Justin Bieber is the source of her frustrations right now.
'Selena is in a really bad place at the moment - she's on the edge and now overcome with jealousy,' a source told British newspaper The Sun.
'She really needs to wash her hands of Justin for good.'
Apparently Selena was convinced Justin, 20, flirted with Kylie, 16, shortly after all three of them hung out together at Coachella in Indio, California last weekend.
Selena and Justin were pictured cuddling together at the festival, which fuelled reunion rumours, but it is claimed she now wants nothing to do with him.
'Selena is convinced something has gone on between Justin and Kylie,' the insider said.
'At Coachella they looked to be back on track. Selena was hanging out with Kylie too and they were behaving like best friends.
'Then she heard stuff about Justin and Kylie and felt totally betrayed. She went berserk and called it all off again.'
The former Disney star has had a challenging few months. In addition to dealing with her on-again-off-again relationship with Justin, Selena recently fired her mother and stepfather as her managers.
She has also been deposed to testify in an assault case that is currently pending against Justin.
