Los Angeles - Niall Horan partied with Ariana Grande in London following her sold-out concert at The O2 on Monday night.

The One Direction heartthrob first went to Ariana's show, part of her The Honeymoon Tour, and then joined the Love Me Harder singer backstage.

This girl blew me away! She has the most incredible voice I've ever heard! Superstar.

The pop pair were then later seen hanging out at Soho night spot Cirque De Soir until the early hours of Tuesday, but each travelled to the club on their own and left separately.

Website Mirror.co.uk reported their evening out was brought to a sudden end after an electrical fault at the club resulted in three fire engines racing to the venue.


Earlier in the evening, Ariana was excited to get to meet Harry Potter stars Matthew Lewis and Evanna Lynch backstage at The O2 and introduced the pair to her pet dog Sirius - who is named after Harry Potter character Sirius Black, who is able to take on the form of a canine.

The massive Potter fan took to Instagram to post a selfie of them all having a magical time.

The photo of the pop princess with the two actors - who played characters Neville Longbottom and Luna Lovegood - was accompanied by a caption which read: "Neville, luna and sirius all in one photo. @msevylynch told me i'm the sweetest Slytherin she's ever met. thank you @msevylynch @realmattdavelewis for coming to my show and making my night!!! i adore y'all.
