Stefani, her goddaughter Stella and her three sons — Kingston, 11, Zuma, 9, and Apollo, 4 — have been spending spring break on Shelton’s home estate. The couple met while participating as judges of “The Voice” in 2015 and spent the last month apart as Shelton went on the Country Music Freaks tour.

Stefani documented the nature-filled spring break trip with posts on her Instagram.

Shelton was previously married to country singer Miranda Lambert, who recently split from her boyfriend of two years, Anderson East. Stefani was married to Bush lead singer Gavin Rossdale until their divorce was finalized in 2016. He is the father of Stefani's three sons.
