Gavin Rossdale gave rare insight into his coparenting dynamic with ex-wife Gwen Stefani more than 10 years after they called it quits. "It is an interesting kind of [relationship]," Rossdale, 60, told Fox News Digital on Monday, March 30, of his relationship with Stefani, 56, as coparents to their three sons. "It's a two-lane highway, you know, but they don't ever seem to merge, which is fine." The Bush singer - who shares Kingston, 19, Zuma, 17, and Apollo, 12, with Stefani - explained that it's not a bad thing that he and his ex stick to their own lane while raising their kids.
