Jack in the Box Roost Fries TV Spot, 'French Fries With Cheese: $3.50' Featuring Jason Derulo

Jack is teaming up with singer-songwriter Jason Derulo to create a hit track for the restaurant's Roost Fries. After the two finish their last take, they excitedly talk about how their collaboration is going to make the side dish world-famous. There's just one last thing to do: Jason needs to wear a French fry costume and pose for some pictures. While originally reluctant to put on the silly outfit, the musician succumbs to his fate as the new mascot for fries. You can try Classic or Spicy Roost Fries for a limited time at Jack in the Box.
