Justin Bieber Gives Kelly Osbourne Graffiti 'Lessons' Amid 'Amicable' Fiancé Split

Justin Bieber, Kelly Osbourne, and graffiti have never appeared in a sentence together. Until now.

On Wednesday night - the same day that Us Weekly exclusively announced Osbourne and fiancé vegan chef Matthew Mosshart had ended their engagement - the 29-year-old posted two Instagrams showing her receiving graffiti lessons from the teen heartthrob.

In one photo, a purple-bobbed Kelly is seen holding her hands up self-deprecatingly while standing next to the pop star, with a spray-painted wall adorned with colorful images in the background.

The other shot shows the retro-80's styled Fashion Police host putting finishing touches to a green 'angel' turtle image.

Justin is seen turning around to look around at her work.

The Instagram was captioned:

"Just had so much fun getting lessons from @justinbieber on how to #SprayPaint! Needless to say I was s*** all I did was the horns! Justin is a lovely boy and have turned me into a true #Belieber tonight!"

It's likely Osbourne's decision to spend an evening tagging graffiti with Bieber was an attempt to lift her mood after the official ending of her engagement.

Justin Bieber Cheers Up Kelly Osbourne With Graffiti Session After Ending Of Her Engagement To Matthew Mosshart The released statement read:

"Kelly Osbourne and Matthew Mosshart have decided to end their engagement. The split is amicable and the pair continue to have nothing but the utmost respect for one another. Kelly is looking forward to a new year full of fresh beginnings.

No further comments will be provided by all parties and we request privacy, decorum and space from the press but don't expect it."

Mosshart proposed to Kelly on New Year's Eve 2012 after meeting at Brit model Kate Moss' wedding back in July 2011.

The chef is the brother of Alison Mosshart from The Kills band, which Moss's husband, Jamie Hince, is a member of.

Kelly may have hinted at at trouble in her relationship when she tweeted a cryptic message on January 8, writing:

"Its all about perception sometimes the bad things that happen in life aren't really bad at all especially when you learn something from it!"

Naturally, those wedding plans have now been scrapped.

But while she may not be engaged any more, Kelly can at least add budding graffiti artist to her resumé.

And Justin Bieber - who, lets face it, has had plenty of practice - taught her how.
