Kellie Pickler and Kyle Jacobs from the CMT show “I Love Kellie Pickler” drive up to a Sonic and try to decide on which Transformers-themed Slushes to get. As soon as Optimus Prime’s voice booms out from the intercom, Pickler knows that she’s choosing his drink, but Jacobs isn’t so sure. Even after Megatron insults the couple, the indecisive musician still opts for his Slush, much to the chagrin of his wife. Customers can enter the Transform Your Summer Sweepstakes for a chance to win prizes by purchasing one of the limited-edition Slushes. “Transformers: The Last Knight” hits theaters June 21, 2017.
