Justin Bieber delights his army of Beliebers as he hands out roses to fans following London show

Justin Bieber went above and beyond for his legion of followers after his barnstorming performance at London's O2 Arena on Saturday.

The Love Yourself hitmaker probably made some of his Beliebers year after he handed out roses to a selection of female fans who had followed him to Tape nightclub following his show.

According to onlookers, the Biebs had bought the pretty flowers off a vendor in the street before he decided to surprise some lucky ladies with their very own rose.

Surrounded by security, Justin had his waiting fans jumping for joy as he made his way to the crowds desperate for a glimpse of him.

Armed with a selection of white, pink and red roses, Justin couldn't hide his smile as he saw the excitement on the faces of his screaming fans who had waited for hours to catch a glimpse of their hero.

Covering up in an oversized Purpose Tour emblazoned hoodie, Justin spent a little time outside before making his way into the venue to toast the end of his first leg of London dates before he returns next month for two more performances at the O2.

Meanwhile, one lady who would have been ecstatic for a rose from Justin is Harper Beckham.

David Beckham 's daughter appeared to be loving Justin's show after her doting dad took her along to one of his recent performances.

The star shared a clip of the five-year-old waving her arm over her head on his Instagram story, as she sang along to the Biebs.

Holding a phone up in the air, Harper is seen leaning on the railing of her private box as she listens to the star belt out his hit Life Is Worth Living.

David added a huge "JB" over the video to clear up any doubt over who his daughter was supporting.

Wearing a dress for the night out, Harper already looked in her element as she joined the screaming crowd.

Meanwhile, the whole family were pictured as they left the concert, with Brooklyn joining his dad in the front of the car.

All wearing caps to match up, the star's sons failed to smile as they left the Purpose concert - no doubt tired out.

And it comes after Victoria gushed over her hubby's parenting skills, admitting she couldn't manage work and personal life alone.

"It is difficult to maintain it all in terms of being a wife, mother and businesswoman leading a brand," she told November edition of Vogue Australia. "But I have a great team and I have a husband who is incredibly supportive."
