Katie's Moral Support? Nicole Kidman

As Katie Holmes was secretively preparing to divorce Tom Cruise, she turned to none other than one of his ex-wives for "support and help," a source says. Katie and Nicole Kidman have "spoken over the last few weeks," the source tells Us. "Nicole has been supportive, saying she's been through it too and to hang in there." Apparently the two have been "private friends" ever since Holmes married Cruise and became stepmother to Kidman's children, the source notes. (Another interesting apparent source of moral support for Katie: Victoria Beckham, fellow Scientologist and good friend to Tom.)

As for Suri, if you were wondering where Cruise's rumored $40 million settlement is going, an expert tells E! that he estimates the 6-year-old's upkeep could cost $80,000 to $100,000 per month (think nannies, schooling, security, and of course, clothes). A rumored additional expense? A name change Katie is considering to Suri Cruise Holmes. Can't get enough of the TomKat divorce?
