Sam Smith has reportedly split from Brandon Flynn.

The 26-year-old singer has been in a relationship with the '13 Reasons Why' actor since November last year, but according to sources, the pair decided to call it quits last week after nine months of dating.

A source said: ''Sam and Brandon had a real whirlwind romance. They really fell for each other. But they are both so busy with their careers and unfortunately things just haven't worked out.''

Sam - who has deleted a number of snaps of the pair from his social media accounts - is said to be ''devastated'' about the split, as 24-year-old Brandon was ''the most significant'' romance the 'Too Good At Goodbyes' singer has had.

The insider added to The Sun's Bizarre column: ''Sam is obviously devastated. This is the most significant relationship he has ever had. Thankfully he is on tour across the US at the moment which has been a welcome distraction.''

The news comes after Sam was spotted enjoying a spontaneous night out in Massachusetts on Sunday (06.24.18), after he turned up with a small group of friends at a nightclub named Candibar.

An eye witness said at the time: ''I don't believe he was drinking. I don't think people recognised him. I would have thought people would swarm him, but it didn't happen. The people he was with were trying to prevent people from taking photos/videos.''

Brandon was not with Sam at the time, as he was celebrating gay pride in New York with his co-stars Tommy Dorfman and Kate Walsh.

Meanwhile, the 'Stay With Me' musician previously said he was excited to finally pen some ''happy love songs'' after finding love with the actor.

Speaking in January, he said: ''I'm in a relationship right now and for the first time, I think I deserve to be happy. I'm actually asking myself if I'm going to be writing some happy love songs soon.''
