Harry Styles Parties with Pixie Geldof, Heated One Direction Fans Send Model Twitter Death Threats

British model Pixie Geldof was recently spotted partying with One Direction heartthrob Harry Styles, and some One Direction fans aren't too happy about it. Geldof and Styles were seen leaving London's Groucho club together last week, and on Monday the duo hit up Soho's Lucky Voice karaoke club - sending many One Directioners into a tizzy which resulted in Geldof receiving many heated death threats on Twitter.

Geldof and Styles teamed up to party with mutual friend DJ Nick Grimshaw on Friday in celebration of his new gig on the Radio 1 Breakfast show. Popular British television host Alexa Chung joined the duo on Monday, as they belted out tunes at the karaoke hotspot in honor of Geldof's birthday. According to one onlooker, "It certainly seemed like a relationship was blooming between them!"

Is a relationship indeed budding between 18-year-old Styles and British socialite Geldof? Not if One Direction fans have a say in it! After photos of the two stars partying together popped up online, many Styles supports took to Twitter to voice their disapproval. One threatening tweet read, "I hate you bit##, fu## I'll kill you." Wow, intense.

Grimshaw tried to shed some light on the matter, tweeting Geldof on Tuesday,

@grimmers: "Reading some of @pixiegeldo1's death threats. Lol."

However, it looks like some One Direction fans have targeted the wrong girl - Styles is supposedly currently dating 20-year-old model Cara Delevingne. Styles even attended the Burberry show at London's fashion week to watch Delevingne walk the runway. According to onlookers, there was definitely "chemistry" between the two. And get this, Delevingne is a good friend of Geldof - supposedly she and Grimshaw are the ones that hooked the duo up! So is Geldof just Style's go-to party buddy? Oh, the dating drama surrounded these One Direction boys!
