Glover picked her victim up by her hair and banged her head against the toilet
A former Playboy Model of the Year has been given a suspended jail sentence for hitting another woman's head against a toilet up to 10 times.
Louise Glover, 26, formerly of Essex, was convicted of attacking Maxine Hardcastle, in Brighton in 2007, following a trial at Hove Crown Court.
She was sentenced to 30 weeks in jail, suspended for two years, and 180 hours of unpaid community work.
Judge Charles Kemp described it as a "vicious and unprovoked attack".
He said Glover was motivated by an "irrational surge of jealousy".
He added that, more worryingly, there was a "complete absence of any sign of remorse" from Glover.
Glover, who had denied the charge of assault occasioning actual bodily harm, was told to "shut up and listen" by Judge Kemp after she repeatedly called out from the dock.
At one point he warned her she faced being taken down to the court cells if she did not keep quiet.
Glover was also ordered her to have no contact with Miss Hardcastle - the daughter of 1980s musician Paul Hardcastle - for the next 10 years.
Judge Kemp told Glover, whose last UK address was Audley Gardens, Loughton, Essex, the attack still had an emotional and psychological impact on her victim.
He said Miss Hardcastle was unable to enjoy nights out and remained self-consciousness as a result of her hair having pulled out.
During the trial the court heard Glover invited Miss Hardcastle and her friend, Nancy Stillwell, to an appearance she was making in Brighton on 15 December 2007.
They were part of a 10-strong party which moved on to the Oceana nightclub in the early hours.
Jurors heard the three women ended up in a toilet cubicle, where Glover became agitated and accused them of looking at her husband - from whom she is now estranged.
The court was told she then hit Miss Hardcastle, breaking her nose and making her hit her head on the cubicle.
Playboy's Model of the Year 2006 repeatedly hit her victim's head against the toilet and then tried to force her head down the bowl.
The attack ended after Glover's husband was heard outside the cubicle telling her to stop.
Glover later claimed she acted in self-defence after Miss Hardcastle became emotional and hysterical about apparent family problems.
She had claimed her victim had sustained her injuries when the cubicle door was kicked in.
