Gwen Stefani and Blake Shelton always sing to each other

The Anaheim, California native, 48, told Giada De Laurentiis, 47, on Monday that she and her beau Blake Shelton, 41, continually communicate with one another using their superior skills as singers. 'We're like we're in a musical constantly and we just sing,' the Make Me Like You artist told the Food Network personality during a segment on Facebook Live for Williams Sonoma, in which the two baked an Apple Parmesan Pie.
