Superstar Nicole Kidman worried her friends and fans after catching the flu in the season of corona spread.

Her husband, the famous country music singer, Keith Urban, was forced to leave the Grammy Awards, "urgently" the cause of his wife, Australian star Belle's illness.

The Contact Music website reported today that although the loving couple used to support each other in major events, Keith, 52, walked on the red carpet on his own, because his wife, "52," was at home because of the flu.

Keith was keen to leave the party, which took place on Sunday evening at the Staples Center in Los Angeles, to return to his wife's nursing.

On the other hand, Keith expressed his gratitude for the presence of his wife in "safe hands" in the house, in reference to the presence of their two daughters, Sunday 11 years old, and Feith, 9, in her side.
