Ex-lovers Justin bieber and Sofia Richie sparked reunion rumours after they were spotted at the same nightclub in London on 15 October. While the pop star hit the city's posh club, Tape, after his successful Purpose Tour gig at the O2 Arena; his last fling was also seen partying in the same area, according to reports.

Gossip website TMZ reported on Sunday (16 October) that the newly single Love Yourself singer took some time to interact with fans before he headed to the party.

Although Bieber and Richie were reported to be partying at the same club, they didn't step in together. In fact, Richie was spotted leaving the London club solo.

But, before Bieber risked an encounter with his former girlfriend at the upscale party place, he arranged for a grand gesture to thank his fans, who were patiently waiting for him outside of Tape.

The 22-year-old What Do You Mean hitmaker impressed the Beliebers by handing out white, pink and red roses. Clearly the Bieber devotees were touched by the pop singer's adorable gesture, who handed the individually wrapped roses to his female fans.

Earlier it was reported that, Bieber and Richie's whirlwind romance came to a sudden stop when the former decided to "cool things off" with the 18-year-old model. Shedding light on the duo's split, a source told E! News that their romance was "super-hot and heavy".

"[Bieber] doesn't want a relationship right now, he wanted to cool things down. It wasn't an intentional cool-off. It just sort of happened on its own," the source added.

On the other hand, the daughter of Lionel Richie had gushed about the Sorry singer saying, "We have a special relationship. Justin is very easy to talk to, and that's hard to find with people in Los Angeles."
