A shrine has been erected in honour of Harry Styles' vomit.

Fans of the 'Kiss You' hitmaker have put up a heartfelt banner on the side of a busy Los Angeles freeway after the 20-year-old singer was forced to pull over and throw up there following a night of heavy partying, The Sun newspaper reports.

Harry - who had been enjoying a night out with fellow singer Lily Allen at an LA bar - asked his driver to pull over on the hard shoulder and was spotted, pale-faced and puking at the side of the road on Sunday morning (12.10.14).

Following the incident, super-fans quickly arrived at the vomit spot and put up a sign reading: ''Harry Styles threw-up here 10-12-14.''

It isn't the first time the 'Steal My Girl' singer has thrown up in public.

The One Direction heartthrob also vomited on stage in Pittsburgh in July last year, although he claimed he had simply eaten too much prior to the show.

Luckily, Harry was able to control his queasiness as he helped a fan propose to his girlfriend at their Atlanta gig earlier this month.

Bradley Chisenhall messaged him and his bandmates - Louis Tomlinson, Liam Payne, Niall Horan and Zayn Malik - on Twitter asking them to help him pop the question to Christine Kozlowski at the performance on October 1.

The plea for help was even trending on the site with the hashtag '#1Dproposal' after he tweeted: ''Help me propose to my girlfriend tomorrow night at the show.''

Much to Bradley's surprise, his tweet didn't go unnoticed as mid-way through the show, Harry said to the audience: '''I have a friend in the audience who's called Bradley ... Bradley would you like to bring your girlfriend on the stage?''

The camera then panned to Bradley, who was down on one knee, as he asked his lover to marry him.

The venue was filled with shrieks of excitement and lots of clapping as Harry shouted: ''She said yes!''
