As part of the Niall Horan appreciation society, we can understand why a few OD fans may have been a little upset to see their prince in the arms of another woman. However, "I'm digging her grave" is a bit, um, strong.
The photos in question were posted after both attended The Saturdays star Rochelle Humes' fancy dress birthday party, with Tulisa dressed up as a Disney princess and Niall as Prince Charming, of course!
"As If my little muffin turned up as Prince Charming looooool #bruddafromanothermother," Tulisa wrote alongside the snaps... But it wasn't long until the abuse started flooding her social media feed.
They ranged from: "Who the f*** is Tulisa,' and 'F*** yourself Tulisa,' and "The fact that Niall was with Tuilsa makes me throw up a little bit," to more morbid threats: "I'm digging her grave."
In true Tulisa style the former N Dubz singer didn't suffer in silence, writing: "Listen crazy b****** Niall is my home boy from day, won't take abuse off u [sic] nutta's so pip the f*** down kids #wejustfriends."
