Kelly Osbourne has some advice for Paris Hilton.
The 29-year-old “Fashion Police” host took to Twitter early Sunday to blast the socialite, urging her to “please grow up.”
“There is no need to act like a child,” Osbourne tweeted. “You could of (sic) happily joined us! It’s not 2005 no one cares!”
Both Osbourne and Hilton attended Coachella in Indio, Calif., over the weekend. The Mirror reports that Hilton approached Osbourne in an informal VIP area and called the E! correspondent “a bitch” after she felt ignored by Osbourne.
This isn’t the first time Osbourne and Hilton have exchanged words. In 2005, Osbourne accused Hilton of being a bad influence on young girls, which sparked a feud between them.
But Hilton acted clueless when she replied to Osbourne early Monday.
“@KellyOsbourne, getting tweets about us,” she wrote. “I’m confused, as I did not see you once this entire weekend. No clue how these stories get invented.”
