DEMI LOVATO HAS MAJOR BEEF WITH STALKER SARAH: 'STAY THE F**K AWAY FROM ME'

It looks like Demi Lovato must have some serious beef with Stalker Sarah, as she's absolutely kicked off on the infamous uber-fan for an issue involving Demi's younger sister, Madison de La Garza.

Demi really didn't hold back as she left a tirade of furious and harsh comments on Sarah's Instagram, slamming her for being a "fame leech" and warning her to "stay the f**k away" from her and her family.

Demi, who's met Sarah on numerous occasions and posed for several pics with her, launched into a seriously angry rant at the super fan over on Instagram, when she noticed pis of Sarah hanging out with her 14 year old sister, Madison.

This clearly didn't sit too well with Demi, who unleashed ALL THE FURY in a stream of comments on Sarah's account, accusing her of preeying on her young teenage sister and using her for fame.

"THIS IS MY 14 YEAR OLD BABY SISTER. You are a 20 year old fame LEECH. SHE IS NOT YOUR BABE...," Demi wrote.

"For anyone reading this: this girl has no regard for anyone's well being but her own. She completely takes advantage of people, even 14 year olds even though she's 20.

"My family is not afraid to press charges... I'm not your f**king 'girl.' If I was you I would not be asking for pictures. You STALK PEOPLE FOR A LIVING. We are NOT FRIENDS. Stay the f**k away from me and most importantly my family."

Since then, Stalker Sarah has hit back at all the drama by sharing a screenshot featuring messages allegedly sent to her by Demi and Madison's older sister, Dallas Lovato.

Tweeting the pic, Sarah claimed that Dallas had contacted her "when she found out [she] was being attacked in her family's name", and showed fans texts purportedly from Dallas telling her that she's "disgusted and embarrassed for what's gone on."

DRAMA.
