So in love! Nicole Kidman flashes flesh in plunging split gown as she packs on PDA with Keith Urban at Big Little Lies premiere

The 49-year-old stunner wore a plunging split to the thigh gown to the event held at the Chinese Mann on Thursday.

The Australian beauty's frock featured a floral pattern, while her husband, also 49, went for a classic look in a black suit and tie.

Kidman stars in Big Little Lies with Reese Witherspoon, who was also in attendance with her lookalike daughter Ava, Shailene Woodley, and Zoe Kravitz.  

While fellow costar Laura Dern arrived in a burgundy and pink layered dress.

Big Little Lies will begin airing on HBO on February 19.

Meanwhile the actress has optioned the television rights for another bestselling novel, Janice YK Lee's The Expatriates. 

Alice Bell has signed on to adapt the book for serial format with Kidman as a potential lead cast member, according to Deadline.

The show has yet to secure a network or streaming service.

The book centers on three women in New York recovering from recent traumas.

Meanwhile, Kidman is now rumoured to be lifting the lid on her well-guarded private life by penning a 'tell-all autobiography'. 

According to Woman's Day, the Lion actress could earn up to $11 million in sales after releasing the supposed memoir.

Nicole's account of her husband Keith Urban's drug struggles would no doubt also spark the interest of readers.

Country musician Keith has made no secret of how instrumental Nicole was to him kicking his drug addiction, telling Woman's Day that his wife 'saved' him by staging an intervention in 2006, just months after their nuptials. 

'You can't save somebody, they've got to save themselves,' Kidman said during an appearance with The Jess Cagle Interview last year. 

'Which is a very big thing for people like me who go, 'I can take care of you. I can do it'. It's a massive lesson because as much as I thought I can do all the work for him, I can make him better, I can take it away, I can help,' she continued. 

'At some point you just have to say, 'I love you and I'm here when you decide to do the work. And if you don't, then that's it'.
