Katie Holmes reached out to Nicole Kidman for support as she planned her divorce from Tom Cruise.
The 33-year-old actress is said to have been offered a helping hand from Kidman - who split from Tom in 2001 after 10 years together - since the couple split late last month following five years of marriage.
A source told US Weekly: "They've spoken over the last few weeks. Nicole has been supportive, saying she's been through it too and to hang in there.
"Nicole offered her support and help."
Kidman- who has two adopted children, Isabella, 19, and Connor, 17, with Cruise - has been friends with Holmes since 2006, when her ex-husband married the Dawson's Creek star, but she is said to have been more of a "private friend" to the brunette beauty over the last few weeks.
The source added: "She has been a private friend not many people know about."
The couple - who have six-year-old daughter Suri - reached a private divorce settlement on Monday less than two weeks after they split.
It is believed Holmes will get primary custody of Suri and continue to live with her in New York City, with Cruise allowed generous visitation rights, although representatives of the pair are yet to confirm any details of their settlement.
But the couple did release a joint statement earlier this week insisting they are "committed" to working on their daughter's "best interests".
They said: "We are committed to working together as parents to
accomplish what is in our daughter Suri's best interests.
We want to keep matters affecting our family private and express our respect for each other's commitment to each of our respective beliefs and support each other's roles as parents."
Signs up with a Catholic church
Meanwhile, Holmes has registered with a Catholic church in New York.
The actress - who recently split from actor and high-profile Scientologist Tom Cruise - appears to have formally confirmed her return to Catholicism by signing up as a member of the congregation of the Church of St. Francis Xavier, which is located on 16th Street between Fifth and Sixth Avenues.
One member of the church choir told the Huffington Post: "Everyone is thrilled to have Katie join us. She has not yet attended a service, but when she does she will be welcomed with open arms."
It has been widely speculated that Holmes wanted to protect the couple's six-year-old daughter Suri from being exposed to Scientology, but Cruise's lawyer Bert Fields is adamant religion played no part in the 33-year-old actress' decision to file for divorce from her husband.
He told RadarOnline: "Let me be very clear about this. The Church of Scientology played absolutely no role in the divorce settlement talks at all. Period.
"The mere suggestion that the Church was involved in any element of the talks and ultimate settlement is categorically false. Anyone suggesting otherwise is just wrong."
Representatives for both stars have insisted the details of their settlement will be kept under wraps, though it is believed Holmes will get primary custody of Suri, with Cruise allowed generous visitation rights.
The welfare of Suri was key to the pair resolving their split amicably and privately following initial speculation there would be a public court battle.
