Nathan proposed to Rebecca on December 23, 2015 at Terranea Resort in Rancho Palos Verdes, CA. The proposal took place during sunset at a special spot of theirs overlooking the ocean. The Fast and Burke families were both present to witness the special moment. Lilly hid close by, watching the whole thing with excitement. She couldn't have been more thrilled. That is until she receiveded her very own ring from Nathan! With that ring, Nathan made a promise to Lilly. The promise was to not only love her mom and be her mom's husband but to also be Lilly's dad. To be a family. To be #FastAtLast.

On June 20, 2016, Rebecca and Nathan welcomed a beautiful baby girl into the world, making them a family of four. Scarlett Lee Fast was the perfect little addition to the Fast Clan and made for a very happy big sister, Lilly.
