The I Will Never Let You Down hitmaker, 23, sparked rumours of a new romance with Ricky Hil after they were spotted holding hands while dining at Nobu in London on Saturday night (05Jul14), before heading to the Drury Club to party.
Hil, 24, has also been showing off his blossoming relationship with Ora with images on his Instagram.com page, uploading a picture of the rumoured couple cuddling for a snap last week (ends04Jul14).
A source tells Britain's Mirror newspaper, "They really hit it off when they met and really like each other, so Rita invited him over (to Europe) to join her. They want to see where things might take them - they're just having a lot of fun."
Ora and Scottish dance star Harris announced their on/off romance was over for good in early June (14), confessing they had called time on the relationship "some time ago". She previously dated Kim Kardashian's younger brother Rob.
