Tulisa, whose drugs trial collapsed on Monday, has been found guilty of attacking a celebrity blogger at V-Festival in Chelmsford, Essex. The singer was accused of hitting celebrity blogger Savvas Morgan, who currently stars in The Only Way Is Essex, during a drunken altercation.
She was found guilty by a judge at Stratford Magistrates' Court in east London. Her assistant, Gareth Varey, was cleared of threatening behaviour.
Earlier this week, a drugs trial against Contostavlos collapsed at Southwark Crown Court after the judge said there were "strong grounds" to believe that undercover reporter Mazher Mahmood - known as the Fake Sheikh - had lied in the witness box.
Stay posted for further updates.
UPDATE: She has been fined £200 and ordered to pay a £20 victim surcharge, £100 compensation and £2,700 costs
