Nicole Kidman and her ex-husband Tom Cruise shocked party-goers at the Vanity Fair Oscar soiree when they enthusiastically chatted with each other and introduced their new spouses.

Meanwhile its been revealed the Hollywood star Nicole Kidman is to make a cameo appearance in cosmetic surgery drama Nip/Tuck, playing a nose job patient.
