Rihanna and Drake were spotted kissing at a London nightclub on Monday (10.03.14).

The pair, who are rumoured to have got back together, were seen at circus-themed night spot Cirque Le Soir, where they got steamy in front of partygoers and didn't seem to be worried about their public displays of affection.

A source said: ''There's definitely no question about their romance anymore. Rihanna and Drake spent the whole night with their tongues down each other's throats and didn't seem to care about everybody seeing.''

The 'Diamonds' singer and the rapper arrived together but left separately and were treated to an exclusive preview of the venue's latest acts as part of its $800,000 Frat Party installation, which included a scary clown sitting in a bathtub filled with baked beans, cross-dressing prom queens and contortionist cheerleaders.

Rihanna, 26, has been travelling with Drake, 27, across Europe in recent weeks while the 'Started from the Bottom' rapper performs in a number of cities on his latest tour.

The 'Take Care' collaborators also dined together at London's exclusive Nobu restaurant on Saturday (08.03.14), arriving ''hand in hand'' before joining a group of friends.

Rihanna previously enjoyed a night out with Drake in Amsterdam last week, and the pair visited Paris nightclub Soixante Dix Neuf last month.
