The American-Irish actress has worked alongside fellow Irish actor Paul as an unhappy married couple in the sci-fi drama, Foe. 

During the festival, Paul was pictured allegedly sniffing a suspicious substance from a bag as he partied with pals at Glastonbury on Sunday. 

According to The Sun the Irish actor used a key as a scoop to raise the unknown material to his nostril while dancing in the crowd during US band The National's late night set. 

Paul was dressed casually and donned a baseball cap, with one onlooker telling the publication the actor 'didn't seem to care' if anyone could see him.

Saying: 'Paul looked like he used a key to scoop some substance out of a bag which he lifted to his nose and sniffed.

'He did it once then he dipped the key back into the bag and lifted it to his nose and sniffed again.

'Paul didn't seem to care if anyone could see him. He was dancing and laughing with his friends.'

MailOnline have contacted Paul Mescal's reps for comment.
