For the first time ever as a 90-minute holiday special, Freeform's "Pop Up Santa Holiday Special" has teamed up with sponsors to celebrate the spirit of the season through heartwarming moments including a home giveaway, a surprise baby shower at a military base, a family reunion of epic proportions, a celebration for two very special children at Children's Hospital Los Angeles and more. Hosted by Stephen "tWitch" Boss and Allison Holker, the special follows celebrity guests including ballerina Misty Copeland, former NFL athlete DeMarco Murray, "The Fosters'" Sherri Saum, Tommy Martinez from new Freeform drama "Good Trouble," a special Marvel guest and, of course, Freeform Santa as they team up with Freeform to spread holiday cheer.
