Kate and Oliver Hudson are sibling goals. As the brother-sister duo answered fan questions during the Monday, July 21, episode of their "Sibling Revelry" podcast, one listener asked Kate, 46, and Oliver, 48, to reflect on a moment where they "really leaned on each other." Kate said the "biggest time" Oliver was there for her - and son Ryder Robinson, now 21 - was after she divorced from Chris Robinson in 2007. "For me, with you and my divorce, with having Ryder and being a working mom, I felt like you really stepped up without me asking," Kate said.
