Nicole Kidman sings eerie cover of 'Dream A Little Dream Of Me' for her new TV show

Nicole Kidman is showing off her impressive vocals once again in her latest television role.

After singing her way into the hearts of many moviegoers with her Oscar-nominated part in Moulin Rouge, the 53-year-old is now crooning an eerie rendition of 'Dream a Little Dream of Me' as the theme song of her new HBO thriller, The Undoing. 

The nearly century-old song - which was first recorded by Ozzie Nelson, but became popularised by The Mamas & The Papas in 1968 - centers on a besotted person who doesn't want to leave the dream world they’ve built with their lover and return to less pleasant realities.

Kidman revealed how her rendition came about in a recent interview on Zoë Bell’s BBC Radio 2 show, telling the host: "We were in lockdown. We were in Tennessee, in Nashville, and the director [Susanne Bier] sent me a text going, 'Would you sing the title track, 'Dream a Little Dream of Me,' to the series?'

"I was like, 'What? No, I so don't want to do that. My voice is not good,' which is always my reaction, and she said, 'No, no, I think you can sing it.'"

Nevertheless, with a little help from her husband, Keith Urban, who luckily does have a recording studio at home, she went ahead and recorded the song.

Kidman stars alongside Hugh Grant as a married couple in The Undoing.
