Haim will be revealing the name of their new album later today, but before that they've had a little fun with fans.
The Californian trio are following in the footsteps of Kanye West, who gave fans the initials of his album as 'TLOP' several years ago, and asked them to guess it. The answer was, of course, 'The Life of Pablo'.
Whether Haim's 'WIMP III' will be similarly obscure remains to be seen.
However, if you take a guess at what it might stand for, you may be in with a chance of winning the t-shirt as modelled below.
Some of the best/worst guesses so far include:
Where Is My Purse
Where is My Pizza
Women in Male Positions
Women in Menstrual Pain
Where is Michelle Pfeiffer
Where is Mary Poppins
Warren is My President
Women in Mosh Pits
Take a guess... it can't be any worse than those ones.
