Demi Lovato's ex-fiancé Max Ehrich 'won't leave her alone', pop star seeking legal advice - reports

Demi Lovato is reportedly seeking legal advice to deal with "issues" with her heartbroken ex-fiancé Max Ehrich, who allegedly "won't leave her alone" following the pair's split

E! News reports a source says Ehrich "has been trying to get in contact with her family and friends and they have all blocked him," adding that the 'Cool For The Summer' singer is now in contact with her lawyers. 

Having celebrated their engagement in July this year, Ehrich claimed he only found out he had been dumped by Lovato last month by reading tabloid stories online.

That news triggered a wave of erratic behaviour that included Ehrich posting tearful selfies, sharing Lovato's songs and campaigning for her to win a Grammy - even returning to the beach where he proposed, crying and walking into the ocean fully clothed with paparazzi nearby. 

Earlier this month, another source close to Lovato said the singer was "completely embarrassed" by Ehrich's actions and revealing social media posts

"She wants nothing to do with him," the source reportedly told E! News. 

In a recent Instagram Live video, Ehrich hit out at Lovato's latest break-up anthem 'Still Have Me', which she released shortly after news of the split broke. 

"I hope this makes you happy. Enjoy. You just lost someone who loved you fully, completely, infinitely, for everything," he said during the broadcast. 

"Now I found out that I was used," Ehrich said. 

"But I hope the song is number one because you know what? If that's what someone wants in the material world, here you go, you have it." 

The actor also claimed he was being used as a "pawn in a PR stunt" and seemingly accused his former fiancé of "using her millions of dollars to write false fake news about me".
