Meet Sean Douglas

Those of you who saw the Golden Globes saw Michael Keaton's touching speech to his son. You may not have heard his name before, but you've probably heard his music. Page Six reveals that Sean Douglas, 31, is a singer-songwriter, and has written such hits as Demi Lovato's Heart Attack, and Jason Derulo's Talk Dirty and Wiggle. Douglas also wrote a track on Madonna's upcoming Rebel Heart album. Some personal info about Douglas: His mother, Caroline McWilliams, was married to Keaton from 1982 - 1990, and passed away in 2010. And the reason that Sean's last name is Douglas? So is Michael Keaton's. Michael Douglas, as he was born, had to change his name when he joined SAG, because there was already a famous actor who bore that name. Michael chose Keaton as a nod to Buster Keaton.
