Add yet another shocking schism to the recent spate of Hollywood supercouple breakups. After 11 years of marriage, Tom Cruise and Nicole Kidman — who first found real-life sparks while shooting 1990's Days of Thunder — have announced they're parting ways. "Citing the difficulties inherent in divergent careers, which constantly keep them apart, they concluded that an amicable separation seems best for both of them at this time," said their spokesperson, Pat Kingsley. No word on custody arrangements for the couple's two adopted kids, Connor and Isabella.
