Justin Bieber and Selena Gomez have fuelled speculation they have reunited.

The 'Beauty and a Beat' hitmaker and the 'Spring Breakers' actress split last year following a turbulent two-year relationship, but they were spotted together for the first time in months Thursday riding segways in The Oaks, a gated community in Calabasas, California, where Justin lives.

Twitter user Nick Sanitsky posted a picture of the pair on the unusual mode of transport and wrote: "Bieber and Selena segwaying in the Oaks. She was so nice, so he yelled at us (sic)"

The social networker claimed the 19-year-old singer had "ruined" his celebrity-spotting moment by being "rude" to him, but he enjoyed seeing brunette stunner Selena.

In a series of tweets, he wrote: "Shoutout to @justinbieber for holding up all the traffic in the Oaks. Grow up

"Thanks to @justinbieber told us to f*** off, and his bodyguards blocked the road, so hello to my new followers!

"Gotta admit, I was kinda starstruck by @selenagomez but @justinbieber ruined the moment (sic)"

The pair's reunion comes just weeks after Selena, 21, was said to be in a "bad place" as she was still struggling to come to terms with their split.

A source explained: "Dealing with her breakup from Justin has still been affecting her and she's been in a bit of a bad place recently.

"Her family stepped in and basically advised her to either go to therapy or stay with them so they could watch over her. Her team agreed that family time would be best."
