Which famous MUM has Justin Bieber been flirting up a storm with?!

Well, there goes our breakfast!

Days after the whole Orlando Bloom drama, the Kardashians flew out to Ibiza to show their support for pop star Justin Bieber.

And the 20-year-old singer wasted no time in getting a tad flirty with momager Kris Jenner…. WTF?!

The Kardashians flew to the party island to celebrate the birthday of Riccardo Tisci, the creative director of Givenchy.

Kim shared snaps of the night with her mum, hubby Kanye West, Baby singer Justin and younger sister Kendall Jenner.

Justin posted a flirty snap of him and Kris, and made a joke about being Kendall and Kylie’s dad with the caption, “@kendalljenner @kyliejenner who’s your daddy.”

OK we know he was probably (we hope) only kidding, but STILL!
