Actress and New York Fashion icon Kristin Davis has a big heart. On HGTV's Celebrity IOU, she gave back to a friend and fellow single mother, Tiffany. The two have been a constant source of inspiration and guidance for one another for nearly a decade. “There are so many memories we’re going to make here,” said Tiffany upon seeing her new home. “We’ll have to have parties a lot,” added her daughter, Lyric. Property Brothers Drew and Jonathan Scott stepped up to help Kristin transform Tiffany’s home into a functional space flooded with touches of modern glamour.
