Social media users have launched a desperate search for a father-to-be after a woman's crude poem telling him that she is pregnant was found unopened on a nightclub dancefloor.

The cheekily penned note has gone viral after the club uploaded the letter to social media after cleaners found it on the floor of Pryzm.

The letter, which instructed the man to open the note at midnight on New Year's Eve, was found on the floor surrounded by debris from revellers.

Now the Nottingham nightclub is seeking the man, known only as Josh, in a bid to reunite him with the announcement.

It read: 'Josh, "Special" is what I'll call the last few years, I'll be collecting you later after you've had a few beers.

'There's a reason I couldn't come with you tonight, I've asked for this letter to be given with you at midnight.

'I hope when you read this you'll be filled with joy - the question is, girl or boy?

'Happy New Year, I hope you've had fun; maybe next time baby... Love, Sarah XXX.'

Pryzm Nottingham said: 'Our cleaners have just finished cleaning after NYE and have just found this sealed envelope.

'We've just opened it and now we need to know; does Josh know?!'

The note has gone viral and received thousands of comments after the club shared it online last night.

George Hort joked: 'Josh has resealed that envelope and ran away #prayforjosh.'

Maggie Birch said: 'Am I the only one rooting for Josh?! This is sooo cute although somewhat bittersweet.'

And Katie Price added: 'I personally would not write a letter for my man to read announcing my pregnancy while he's smashed at midnight.

'I'd wait until he's hungover af and watch him spew his guts up after I told him the next day.'

Samantha Fryer commented: 'We need to find Sarah and follow her pregnancy journey, she's hysterical.'
