The performance is part of the press tour for her recent album ‘Hold The Girl’, released via Dirty Hit.
The Apple Music Livestream celebrates her 'Happier Than Ever' world tour, which concludes this Friday, September 30th.
Joined by her brother and producer Finneas, the short but special set saw her perform new release 'TV', 'Getting Older', and album title track 'Happier Than Ever'.
They're packaged together under the banner 'Guitar Songs'.
Sat under a single spotlight, there’s the very real sense that this is just a girl, singing her songs in front of an audience, asking them to experience this with her.
Performing earlier tonight (7th June) at Manchester's AO Arena, she gave a first airing to the new cut.
New artists revealed include Sam Fender and Megan Thee Stallion.
There'll be Carly Rae Jepsen, BROCKHAMPTON, Rina Sawayama, girl in red and loads more too.
Titled 'When Billie Met Lisa', it will arrive on 22nd April and feature both Billie and her brother Finneas.
The pair will showcase 'No Time to Die', the song they wrote and performed to the latest instalment in the James Bond franchise.
