Fans took snaps and recorded videos of the couple as they enjoyed a night together at a piano bar, having walked in together hand-in-hand.

Justin even took to the keys and serenaded her with a few songs, including the Beatles' Let It Be, as she sidled up beside him on the bench.

At one stage, Bieber shared a snap on Instagram of their footsie-playing feet beneath the piano - his in flat white trainers, hers in pointed white shoes showing major toe cleavage - but he swiftly deleted it.

The 25-year-old is also set to appear alongside the singer in the video for the much-hyped new song, What Do You Mean, in which she is reported to be playing the main role.

The ex-Victoria's Secret model shot the video in Hollywood last week.

For the past number of weeks, the pop star has been posting pictures of his celeb friends holding up handwritten placards counting down to the single's release on Friday, including Larry King, Kendall and Kylie Jenner, Gigi Hadid, Chris Martin, Ellen DeGeneres, Hilary Duff, Ed Sheeran, Ariana Grande, Big Sean and Mariah Carey.

Kate Hudson even posted a video clip of her playing a snippet of the song on her phone.
