Grant, whose credits include Hairspray, Rock of Ages and Justin Bieber: Believe, will join Schmidt on his upcoming debut tour with solo band Heffron Drive, which takes Schmidt through 20 major cities throughout November and December.
Schmidt is the first of the current boy band stars to go solo, and though he’ll make himself available for Big Time Rush reunions, putting the results on film is a way for him to broaden his horizons.
‘It’s awesome to have Garret along to document this crazy time in my life. It’s scary, it’s new, but it’s a really special moment, debuting Heffron Drive, heading out on tour and reuniting with all the amazing fans. It’s all I’ve ever wanted.’
