It's been a while - three years, in fact - since we last heard new music from Lily Allen, but the wait is over for fans.

The LDN pop star has officially released new single 'Trigger Bang' after it leaked online at the weekend.

It features her fellow Londoner, rapper Giggs - and it looks like we may be in for the follow-up to 2014's 'Sheezus' next year as well as that memoir.

Until then, hear 'Trigger Bang' below:
