Grammy Award-winning singer Michael Bolton has joined forces with food brand Fiber One for its #FiberUp campaign, encouraging people to eat more fiber with commercials titled 'Being Irregular is the Worst' and a video 'Expecting', featuring Bolton's track I Just Can't Wait to Meet You.

Julia Wing-Larson, marketing manager for Fiber One, commented 'Fiber One is known for having a playful nature and love of music. Michael Bolton, a cultural icon known for his humour, was the perfect match for our lighthearted campaign'.
