Selena Gomez is rumoured to have landed a new pop star boyfriend after she was spotted hanging out with One Direction's Niall Horan in London over the weekend (15-16Feb14).

The singer has enjoyed an on/off relationship with troubled teenage singer Justin Bieber over the last few years, but the young couple is said to have ended the romance for good last year (13).

Pictures have now emerged online showing Gomez spending time with Horan in the British capital.

The snaps were taken by fans, who are seen posing with the pair, and they were published on Twitter.com.

Horan is not the only One Direction star rumoured to be enjoying a new romance - Harry Styles has recently been linked to singer Sky Ferreira, according to The Sun newspaper.
