Looks like HAIM don't just plan on releasing their debut album next week – the sister trio look set on world domination, starting with their trip to UK shores. First @BabyHaim (Alana) tweeted this sneak peek of their first NME cover before killing their Live Lounge performance on Fearne Cotton's Radio One show this morning, and announcing her fellow DJ as their new member with the sensational tweet: 'ATTENTION: @grimmers is officially in HAIM. Discuss.' The takeover has begun.
