THE seemingly sudden split of Nicole Kidman and Keith Urban after 19 years of marriage sent shock waves through Tinseltown, but insiders reveal the image-conscious pair have been living a lie for months — and he's already cuddling with a new galpal!

Sources snitch that 57-year-old country crooner Keith pulled out of the marriage in June and moved into his own pad in Nashville while Nicole, 58, desperately hid their rift from the public as she battled to save the relationship before realizing it was kaput and filing for divorce on Sept. 30.

“Nicole was stunned and betrayed by Keith’s decision to split, and she’s still trying to process it,” says the insider.
