Meryl and Nicole have already been shooting scenes for the upcoming episodes, and despite being no stranger to the world of acting herself, the Australian star often feels in awe when she works with the three-time Oscar victor.
'We've already been shooting, ' she said.
Keith Urban hit the stage during the ACM Awards on Sunday night to perform his new single "Coming Home" with pop singer Julia Michaels, and the performance was a clear hit on social media. "She's just wonderful, and to watch her do her craft, it really is artistic craft when you watch her, we're all - Laura Dern, Shailene [Woodley], Zoe [Kravitz], Reese [Witherspoon] - we just go, Gasp, can you believe it?".
Triple-Oscar-winning Meryl plays Mary Louise Wright in the show, mother of Perry Wright (Alexander Skarsgard), Celeste's deceased husband. And she promised she and her castmates are doing everything they can to ensure the second season lives up to fans' expectations.
"She's got a fantastic character", she continued. "It's also grounded and it's based in something very, very real, and we hope we bring you the (best) second season and it delivers".
While Meryl rarely does TV work - that last time was in 2012 - she has obviously been won over by the critically-acclaimed HBO hit, with it's award-gathering first season boasting plenty of meaty roles for women.
"I love that she's joined this insane cast and this incredible Big Little Lies", Urban said ahead of his ACM Awards performance. I wouldn't go on camera", Urban stated, adding, "I love being on set where Nic is.
Nicole queried: 'He might do a cameo, wouldn't you?.
