On-off pals Kelly Osbourne and Paris Hilton reignited their feud yesterday during the first weekend of the Coachella festival.
According to eye-witnesses, Kelly was chatting with friends in one of the event’s informal VIP areas, when 33-year-old Paris came over and tried to join in with the group.
It's unclear why, but the heiress allegedly then glared at Kelly and stormed off, accusing Sharon and Ozzy's famous daughter of being a “b*tch”.
The girls have been 'friends' for years
Shortly afterwards, 29-year-old Kelly decided to tweet about the incident, writing, “Please grow up, there is no need to act like a child you could of joined us it’s not 2005 no one cares.” (sic)
Paris called Kelly a 'b*tch
A source told the Mail Online: “As far as Kelly is concerned, this is something out of nothing. Paris is being ridiculously sensitive and attention-seeking.
“Kelly was sitting with some mates, minding her own business, when Paris suddenly started bitching and moaning, and slagging her off.
“She was asked by someone else to join the group, but declined and swanned off. The pair didn’t speak for the rest of the weekend.”
Kelly thinks Paris acted 'like a child'
But this isn't the first time the girls have had a public spat.
Eight years ago Kelly accused the millionaire heiress of being a “bad influence” on young girls.
And then it was the turn of the E! Presenter to feel Paris's wrath, after the socialite and her then boyfriend, shipping heir Stavros Niarchos, reportedly ruined Kelly's 21st birthday in Las Vegas bash by trashing her hotel room.
The duo have kissed and made up since then, but for now at least, it seems like they're back to their old ways.
