Former N-Dubz singer Tulisa Contostavlos has protested her innocence and vowed to launch an appeal after she was found guilty of assaulting a celebrity blogger at the V Festival.
Contostavlos, 26, said she was "outraged" after she was convicted of hitting Savvas Morgan during an altercation at the music event in Essex last year.
The ruling was made by a judge at Stratford Magistrates' Court today.
In a statement read after the verdict, Contostavlos said: "This has been a rollercoaster week for me. I never wanted any of this.
"I did not assault Vas J Morgan and I am outraged at this decision. I will be appealing it.
"There are a number of high-profile witnesses who were there and know what happened. I urge them to come forward and tell the truth at the appeal.
"I am determined to clear my name as I have already done once this week.
"I repeat - I did not assault Vas J Morgan. I am innocent."

Her assistant, Gareth Varey, was cleared of using threatening behaviour during the incident in August last year.
After being convicted of the assault, Contostavlos was ordered to pay a total of £3,020.
This consisted of a £2,700 contribution towards the cost of the prosecution, a £200 fine, £100 compensation to Mr Morgan and a £20 victim surcharge.
Morgan said after the conclusion of the case: “I'm pleased we can finally put an end to this and move on.
"It's been a difficult time for everyone involved and I'd just like to put it behind me. I've had my character questioned and now feel vindicated by the verdict."
Earlier this week, a trial against Contostavlos was thrown out 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" at an earlier hearing.
Contostavlos had vehemently denied brokering a drugs deal, which had been reported in The Sun on Sunday last year.
Mahmood has been suspended by the paper pending an internal investigation.
