Earlier this year,
And now, they're back for round two.
It all started Thursday (August 27), when Hilton posted a photo of Allen on his Web site featuring the standard Perez treatment (lots of crude doodles) and the headline "Lily Allen + Motherhood = Disaster."
In the accompanying text, Hilton linked to a recent interview Allen had given to the U.K.'s OK! magazine, in which she said she wanted to retire from the music business and raise a family on a farm. Hilton then expounded on her virtues as a mother, writing: "Bad Idea! ...We forsee the afternoon Lily gets so drunk she confuses the playpen for the pig pen and her baby has to waddle in mud for hours before someone notices ... can't [Allen] stick to intoxication instead of moving on to procreation? It's what [she] knows best!"
Somewhat understandably, this upset Allen — who reportedly suffered a miscarriage last year — and she took to her Twitter account to call Hilton "an evil bastard," then wrote, "I hate this man. Someone better watch themselves. And yes, that is a threat."
Hilton responded with laughter (seriously, he tweeted "Ha ha ha ha!") then wrote, "I love you too! xoxo."
Meanwhile, an Allen fan had sent a message to the singer, assuring her that Hilton "wasn't worth the effort," to which Allen responded "maybe worth a few phonecalls though," suggesting that Hilton might be hearing from her lawyers.
A spokesperson for Allen had not responded to MTV News' request for comment on the matter at press time.
Hilton then fired back, telling Allen, "I'm worth more than that," then tweeting a link to his Gap-sponsored fashion Web site and suggesting that she should read it alongside reality TV mom Kate Gosselin.
At press time, Allen had maintained Twitter silence, possibly signaling the end of this bout. Hilton, on the other hand, has since gotten back to business as usual.
