BeforeNicole Kidman was married to Keith Urban, she was married to Tom Cruise.
Since her current husband is notably a country singer, she must have been referring to Cruise.
It was their 1990 film “Days of Thunder” that helped catapult Kidman into Hollywood stardom.

So it makes sense that Kidman would give a small nod to him.
She also seemed to be gesturing to her daughters and other family members sitting with Urban.
Urban and Kidman have two daughters together Sunday Rose and Faith Margaret.

Kidman’s children with Cruise didn’t attend the event, nor did Cruise.
