1D pursue the American socialite siblings in the US

One Direction have been making moves on the Kardashian sisters.

During a US radio interview in Pennsylvania, Harry Styles held up a poster of a bikini-clad Kim Kardashian with a rather unsubtle Post-it Note attached that read: ‘Call me, maybe? ;)’

But while Harry, 18, waits to be acknowledged by Kim, 31, his band mate Niall Horan, 18, has had a little more luck with her younger sister, Khloé.

The Irish charmer has invited the socialite and her basketball star husband Lamar Odom, 32, along to 1D‘s Dallas concert.

‘OMG we would love to!! When and where?! LOL depending on if there’s a game we would love to come :),’ replies Khloé, 27.
