Louis Tomlinson drinks a shot with a fan to toast her 18th birthday mid-concert as she celebrates her milestone age

Louis Tomlinson made a fans dream come true on Tuesday night as he drank a shot with her mid-concert to toast her 18th birthday.

The former One Direction star, 34, took to the stage at the OVO Hydro in Glasgow where he paused his show to celebrate a fans milestone birthday. 

The singer looked happier than ever as he chatted with the front-row fan who asked to do a show with him on her special day. 

Louis was heard asking the teenager if she had a shot on her and when she said no, he replied: 'I'll get back to you in one songs time'. 

Like promised, the Lemonade singer returned to the front with two red cups and handed one to the fan. 

Clinking glasses, he said: 'Cheers, cheers, cheers!' 

After downing the unknown alcoholic beverage, Louis took the red cup back and high fived the fan. 

Laughing, he added: 'Horrible right?'

It comes after Louis received a sweet showing of support from his former bandmate Niall Horan, as the singer attended his show in Paris last week.

Niall appeared to show his loyalty to Louis by attending his concert at the Accor Arena in Paris days after claims of his row with Zayn Malik emerged.

Louis send the crowd wild by confirming that Niall was in attendance, and said it 'meant a lot' that he'd come to watch the show.

Footage of the moment, which has been shared on TikTok, showed Louis saying: 'I also wanna say I've got a mate in the house today, somewhere around there.

'So, yeah, shout-out to you Niall. Appreciate you coming today man, that means a lot. Thank you very much.'

Sources claimed earlier this month that a Netflix travel show featuring Louis and Zayn has been shelved after Zayn allegedly punched Louis during filming, resulting in the singer suffering a concussion and requiring medical treatment.

The pair have reportedly not spoken since the incident occurred six months ago, and Louis appeared to confirm the feud by unfollowing Zayn, 33, on Instagram.

Following the 'punching' news, Louis unfollowed Zayn on Instagram, while Zayn still has Louis as one of the 17 people he follows.

The Daily Mail contacted Netflix, Campfire Studios, and representatives for Zayn and Louis for comment.

Since then, Zayn has reportedly been seeking treatment from a cardiologist after suffering a mystery health scare, which forced to pull out of a string of events to promote his new album.

The singer was set to perform in Kingston, UK on April 13 for a special One Night Only show playing new tracks from his new album KONNAKOL, but he told fans he was 'heartbroken' that he had to cancel.

'Heartbroken that I can't see you all this week, I wouldn't be in the place I am today without you guys and am so thankful for your understanding,' he wrote on Instagram, whilst thanking hospital staff.

An insider has now reported that Zayn is seeking further medical treatment from the 'No. 1 cardiologist in the world.'

The source told People.com that the star has had to cancel a scheduled appearance on The Tonight Show this week as he continues to recover.
