Current and former Star Magic artists reunited to celebrate the birthday of former ABS CBN's talent agency head, Johnny Manahan, popularly known as Mr. M. 

In a now-viral post, Kathryn Bernardo, Jericho Rosales, Bea Alonzo, Piolo Pascual, Donny Pangilinan, and Jake Ejercito were seen singing Mr.M's favorite song, Pure Imagination, originally sung by Gene Wilder for the 1971 film Willy Wonka & the Chocolate Factory.

Mr. M's birthday was also a star-studded affair, documented in Bea Alonzo's Instagram post on Jan. 27.
