The musician recently announced his split from wife Gwyneth Paltrow after 10 years of marriage.
The couple released a statement on Gwyneth’s lifestyle website Goop confirming that the pair were ‘consciously uncoupling.’
Since the split, both Chris and Gwyneth have been spotted out with one another, but have yet to be pictured with anyone else.
According to a source, Chris Martin enjoyed an evening out with fashionista Alexa Chung.
The source told heat magazine: ‘When I arrived, about 9:15 p.m., they were tucked away in a dark corner of the back room of the bar.’
‘Chris and Alexa seemed to know each other really well. They were both in a great mood, and even asked us to watch their bags when they went out for a cigarette. It definitely looked like a date to me.’
The sighting comes after Chris and Alexa were spotted together at Glastonbury last year.
The source revealed that though they looked friendly, it did not seem as though anything romantic was happening between them at the time.
‘They turned up together at around 3 or 4am and came over to where I was working at Shaken Udder and said to me and my friend 'what do you recommend?'
‘They looked like they were just chilling and having a good time. I did find it a little odd that they were together – but we had a little chat and they wandered off after they asked us if we knew of any good places to go and have a few drinks.’
The source added: ‘They were having a laugh together, but it didn't seem that anything was going on.’
Alexa Chung has previously dated Arctic Monkey’s frontman Alex Turner.
What do you think, just friends? Or potentially something more?
