The unnamed landlord is suing Mill after the rapper threw a Grammy Awards party and invited 1,000 guests, according to reports.

The complainant has since added celebrity party guests Bieber, Khloe Kardashian, Nicki Minaj, Chris Brown and French Montana to the suit, alleging they were "trespassers" who contributed to the damage.

However, Bieber filed his response to the lawsuit on Friday (11Sep15), insisting he did not cause any damage and neither did any of his fellow guests.
