Here’s a photo of Mike Posner with Justin Bieber, Alfredo Flores, and Julian Swirsky in London, UK on March 7.

“Enjoying life” – Justin Bieber

“In London w/ @justinbieber @iAmJulkeyz @alfredoflores …all we talked about is how blessed we are.” – Mike Posner

I have no idea when and who shot this photo of Mike Posner in the car with Justin Bieber and Julian Swirsky in London, UK. It was probably most likely taken on March 6, the day the photo surfaced on Twitter & Tumblr. I think it was taken by a fan waiting outside JB’s ‘Believe Tour‘ show at the O2 Arena, his hotel, or perhaps someplace else in London. Check it out!

Here’s a photo of Dan Kanter, Musical Director and Guitarist for Justin Bieber, and Mike Posner backstage at JB’s ‘Believe Tour‘ stop in London, UK on March 4. I don’t know why Mike snuck out of the US and went to London, UK without telling anyone, LOL. Not sure if he’s just there for JB or there working on his own music or for someone else.

“New songs backstage. :)))” – Mike Posner

Mike Posner was a surprise guest/performer at Justin Bieber’s ‘Believe Tour‘ Orlando show last Fri. night, and then went to Miami for his last 2 US shows before JB takes his tour overseas to the UK plus several other countries. Mike didn’t perform Sat., but he did last night with several other special guests that included Big Sean and Ludacris. I believe Mike sang his hit song “Cooler Than Me“. They filmed both Miami shows for another JB movie, so perhaps Mike will be featured in the film too.

“Up all night with my brothers. Couldn’t ask for anything more. Shouts to @mazy” – Mike Posner

I know that Mike is in Miami currently, and so is Justin for his last 2 ‘Believe Tour‘ concerts in Miami tonight and tomorrow. Mike Posner, Maejor Ali, Justin Bieber, Spiff TV, JB’s DJ – DJ Tay James, and Shaquille O’Neal. Check out the photos below!

Justin Bieber brought out surprise guest Mike Posner on stage at last night’s ‘Believe Tour‘ in Orlando, FL. Mike sings his hit song “Cooler Than Me” for the crowd. It’s a short video and only the beginning of Mike’s performance is recorded, but check it out!

Mike Posner was hanging out with Justin Bieber today and he ended up attending his ‘Believe Tour‘ concert tonight in Orlando, FL. He then surprised everyone when he took to the stage to perform his song “Cooler Than Me“. Check out the photos below; one of him performing and the other of him with JB’s manager Scooter Braun.

“Surprise guest @mikeposner tonight. Known him since his duke days. Great guy. Proud of him!” – Scooter Braun
