The One Direction hunk was spotted leaving a party with model and DJ Pixie Geldof recently and his furious fans have taken to twitter to voice their displeasure and warn her off dating him.
Pixie’s pal, DJ Nick Grimshaw tweeted: "Just reading through some of Pixie Geldof's death threats. Lol (sic)."
According to the Daily Mirror newspaper, the threats include: "I hate you b***h, f**k I'll kill you.”
However, it appears they have targeted the wrong girl as Harry attended the Burberry show at London Fashion Week to support his reported girlfriend Cara Delevingne, who is a friend of Pixie’s.
Fellow guests couldn't fail to see the "chemistry" between himself and runway star Cara.
A source said: "Harry was smirking every time Cara came along the catwalk.
"He kept looking away to avoid putting her off, but you could tell there was chemistry there - even from the audience."
Harry, 18, was first romantically linked with the 20-year-old model - who he met through friends Pixie and Nick - last month after being pictured leaving a party together in the early hours of the morning.
