Suki Waterhouse and Bradley Cooper have reportedly called time on their romance.
E! News claims the 40-year-old actor and the 23-year-old model - who hav been dating since early 2013 - have split up but speculative it might not be for good.
In the wake of the reports American Sniper star Bradley was seen partying in Vegas on Wednesday with a group of his guy pals.
Bradley hit up Elton John's show at The Colosseum at Caesars Palace before heading onto a nightclub. The actor was joined by pals including Jonah Hill and - rather randomly - British comedian Jimmy Carr.
Meanwhile Suki walked the red carpet in New York on Monday night at the Divergent Series: Insurgent premiere and betrayed no hint of upset as she goofed around in front of the cameras.
The pair met at the Elle Style Awards in February 2013 and in an interview with Rollercoaster magazine Suki admitted there was an instant connection.
She said: 'We were introduced and hit it off almost immediately.'
'We were dancing at the after-party, and he asked me if I fancied going to a club. We went to Cirque Le Soir in London – and he's a ridiculously good dancer.'
