Justin Bieber has been playing social networking matchmaker to his pal Julian Swirsky after learning the teen is smitten with Kim Kardashian's little sister Kendall Jenner.
 
The pop superstar tweeted 15-year-old Jenner on Monday, suggesting she should consider going out on a date with his 16-year-old friend.
 
Bieber wrote, "Hey @Kendalljenner you should let my boy @iamjulkeyz take you on a date."
 
And it appears Jenner is seriously considering the idea - as long as the singer and his girlfriend Selena Gomez join them.
 
She tweeted, "Only if you & @selenagomez join! :) #DoubleDate."
