Yesterday (March 31) was Jack Antonoff’s birthday and his current collaborator, New Zealand’s pop wunderkind Lorde, made sure they celebrated accordingly. Now if you’re not sure who Jack Antonoff is exactly, you may know him as one third of Fun. – the guys behind 2011 mega-smash ‘We Are Young’ – or as Lena Dunham’s boyfriend, or as Bleachers, his solo moniker. Antonoff has worked with Grimes (on ‘Entropy’), Taylor Swift (on ‘I Wish You Would’), and Charli XCX (on ‘Rollercoaster’) among many others, and now he’s in the studio with Lorde, which is great news.

The 19-year-old began the strange, reality-TV style series of tweets with the above birthday message, before expanding into weirder, face-swapping, MJ glove-stealing antics. If you’re wondering where the glove is, it’s at Westlake Recording Studio in LA. 

Then they started loitering around a very expensive car. “Can you stand on the back?” asks Lorde. 

This next one is admittedly less impressive: it’s basically just them giggling, drinking smoothies and looking into Lorde’s phone. 

Did Jack have a good birthday? Seems like he did, yes. Because he got to wear this jacket at the end of it, apparently. 

As for what Lorde’s new album sounds like, we don’t know much, but she’s so far said it’s influenced by Robyn and that it’s “totally different” from her debut, ‘Pure Heroine’. Plus, her work with Disclosure last year may have rubbed off a little.
