Deborra-Lee Furness has seemingly shared the reason for her split with Hugh Jackman — and it allegedly involves Broadway star Sutton Foster.

Sources confirmed to Us Weekly in this week’s cover story that Jackman, 56, and Foster, 49, are in a full-blown relationship. Rumors about their rendezvous started late last month when gossip blogger Tasha Lustig claimed that Jackman had “blindsided” Furness, 68, by sharing his relationship with Foster.
