Tom Cruise was back on the set of his upcoming film, "Oblivion," the day after his quick divorce settlement, but he wasn't wearing his wedding ring, People magazine reports. His soon-to-be ex was first seen sans ring on July 2 while filming "Project Runway: All Stars."

Cruise, 50, agreed to a settlement with 33-year-old Holmes Monday after the actress filed for divorce on June 28. The couple has been married for five years.

Meanwhile, one of Cruise's exes has may be helping Holmes through her split. Nicole Kidman has "offered her support and help," a source tells Us Weekly.

"Nicole has been supportive, saying she's been through it too and to hang in there," the source adds of the friendship, which apparently has existed since 2006. "She has been a private friend not many people know about."

Kidman divorced Cruise in 2001. They have two kids, Isabella, 19, and Connor, 17.
