[HIGHLIGHTS] Taylor Swift and Travis Kelce have been fully "embraced" by each other's families

Taylor has become even more close with Travis' mom, Donna. Taylor has also "enjoyed" getting to know Travis' brother Jason and his wife Kylie.

"Travis and Taylor are still in the 'honeymoon' phase and the relationship is serious," a source said. They are on the same page about the future but are not rushing marriage or the next step. The couple have a great system going on. They FaceTime and text a lot when they aren't together.
