Kendall Jenner wants to go on a double date with Justin Bieber and Selena Gomez.

The 15-year-old reality TV star - who is the half sister of socialite siblings Kim, Kourtney and Khloe Kardashian - has taken to twitter to respond to a proposition by the 17-year-old singer, who asked if she is willing to go on an outing with one of his friends - but Kendall only wants to if the popstar couple come along too.

Justin tweeted Kendall to ask if she would be willing to go out with his writer/producer mate Julian Swirsky.

He wrote: "Hey Kendall Jenner, you should let my boy [Julian Swirsky] take you out on a date."

And the model - who recently became the new face of Australian swimwear designer Leah Madden's Summer 2012 campaign Pirouette - replied: "Only if you and Selena Gomez join."

Julian - who is 16, according to his Twitter profile - seems keen on a date with Kendall as he wrote back to Justin: "Yeah, I wouldn't mind that."
