Kidman, 58, filed for divorce on Tuesday, September 30, amid rumors that her husband Urban, 57, is already in a relationship with another woman. If there is someone who knows a thing or two about unfaithful husbands, it's Furness, who was tossed aside by her ex-husband Jackman. The Wolverine star is now dating his The Music Man co-star Sutton Foster. Now it seems Kidman and Furness have bonded over their shared betrayals. "They’ve been inseparable," a source revealed to Hollywood Insider Rob Shuter, who writes on Substack.
