British Beliebers were not happy with their main man Justin Bieber Monday night.

The “Baby” singer, who claimed he planned to "chill with friends" before his London shows, was probably hanging out for  longer than he should have.

The Canadian pop sensation arrived to his concert at the O2 Arena tonight almost two hours late, a horrible start for the first date of his “Believe” tour, E! News reported.

Biebs has not addressed why he was tardy, but it was probably because he was having a good time indulging in other activities. His fans are not pleased with Bieber’s choice to take advantage of their time and have already expressed a demand for a refund because of the delay.

"I was at the concert and he came out at 10:15 p.m. and Carly Rae Jepsen finished her set at 9:10 p.m.. Justin should have been out at 9:30," Belieber Sophia Lee told E! News. "Everyone was kept waiting not knowing anything. All they did was kept playing Michael Jackson songs. All the fans were getting so annoyed at around 9:50 p.m., fans started booing."

Tickets for the JB concert promised that he would step on stage at 8:30 p.m.

Bieber's generally appeals to a younger group of fans, and according to reports many of them had to leave early is it was a school night for them. Others had to quit the concert before it ended to make sure they caught the proper train home.

"I stayed! But many people left early as the last underground train was at 12 a.m., so people needed to get home," Lee continued. "He didn't even apologize. That's what makes it worse...My mom paid for five tickets so she's not happy."

Though Bieber’s camp hasn’t commented about the disappointing concert, The Arena (where he played) tweeted about the incident:

"Justin Bieber is now on stage and apologises for the lateness of his show," and then added, "Sorry to all the Justin Bieber fans for the lateness of his show tonight. The Tube will still be running when the show finishes."
