Jaden Smith takes the stage during Justin Bieber‘s Believe tour performance at the O2 Arena on Thursday night (March 7) in London, England.

The 14-year-old entertainer and longtime BFF to Justin was on hand as a surprise guest during the show.

During the show, Justin collapsed on stage due to shortness of breath and was brought backstage to be examined by a medical team. Despite his doctor’s orders to cancel, Justin returned to the stage to finish his show for the fans.

Later that same night, Jaden was spotted leaving his hotel with his buddy and former Hannah Montana actor Moises Arias.
