Olly Murshas joined One Directionfor a gig on their current tour of the US and Canada.
Former The X Factor contestant Olly flew out to Canada early this week and joined 1D on stage in Toronto with a support slot on Tuesday.
And the happy Essex chappy, 28, was snapped larking about with Niall Horan backstage - appearing to play catch with one of Olly's trademark hats.

After the gig Olly tweeted: "Wow!! Thanks @onedirection fans for an amazing night! Didn't expect such an awesome reception!! Blown away!! Now watching the lads."
He later added: "TORONTO RULES!!!"

Olly has also been added to the bill of the iTunes Festival - a month-long series of concerts happening at the end of the summer.
He will play the Camden Roundhouse on September 3 and told Metro newspaper about his plans for the gig.
He said: "I am going to bring my live nine-piece band and hope that I too can put on a great show.
"I went to see Chase & Status last year for their iTunes Festival gig and it was a brilliant atmosphere.
"It's an amazing event to be part of and one that I have always wanted to play."
