Nicole Kidman is 'laying low' to avoid TomKat questions... (she's even avoiding close friends!)

Nicole Kidman is so determined to stay silent on the subject of her ex-husband's latest split that she's even avoiding her friends.
She's refusing to get involved in the divorce drama unfurling between Tom Cruise and Katy Holmes, even though there are echoes of her 2001 split with the now 50-year-old movie star.

Keeping her head down: Nicole Kidman is keeping a low profile despite arriving in LA with her family on June 22

Not least 33-year-old Katie's decision to file for sole custody of Suri, six, after Nicole, 45, lost primary residence of her two adopted children with Cruise, Isabella and Connor.
But sources tell FOX411’s Pop Tarts that Kidman, who was married to Cruise for nearly 10 years before the actor filed for divorce, is steering clear of even close friends to avoid being drawn on the subject.
'Nicole won’t talk, wants her privacy, wants to be left out of this and they (she and Cruise) don’t speak much,' an insider told RadarOnline.com. 'Communication between her and Tom is very limited.'

The actress, who was said to be shocked when Cruise filed for divorce in 2001 – only two months after they renewed their vows – has kept a hugely low profile since Holmes filed for divorce from Cruise last week.
'Nicole really does not want to be dragged into this or say anything to anyone,' continued the source.
'At some point though, she will probably be forced to say something, and she will most likely support Tom for the sake of their children.'

Hands on: Nicole with her children in 2000, but they would stay with their father after the following year's split

According to one report, after the dissolution of their marriage, members of the Church of Scientology turned Isabella and Connor Cruise against Kidman, calling her a 'sociopath' and the actress has only recently reunited with her adopted daughter.
'I love mom,' Isabella recently told Australia’s New Idea magazine. 'She’s my mom. She’s great. I see her sometimes [in Nashville] and I speak to her.'
Cruise has hired Dennis Wasser, the same lawyer who represented him for his divorce from Kidman.
Kidman arrived in LA with her second husband Keith Urban and their two daughters, Sunday Rose, who turns four tomorrow, and 18-month-old Faith Margaret at the end of June.
