Bieber surprised fans with an appearance at Grande's gig in Miami

Justin Bieber made a surprise appearance at Ariana Grande‘s show in Miami last night (March 28).

Bieber later tweeted: “Thank you @ArianaGrande and thank you Miami. I missed the stage. See u soon ;)”

Justin Bieber is being sued by the neighbour whose house he threw eggs at, with the man claiming that Bieber’s security guard abused him about his religion in a separate incident.

Jeff Schwartz claims that prior to Bieber egging his house in January 2014, his bodyguard shouted anti-semitic abuse at him. Additionally, Schwartz is claiming emotional distress brought on by Bieber’s parties and alleges Bieber spat on him. The singer reportedly denies the spitting.

Bieber recently apologised for his wild antics after a host of stars lined up to mock him during an appearance on US show Comedy Central Roast. Rappers Snoop Dogg and Ludacris were among those to take jovial digs.
