Nicole Kidman and Keith Urban celebrated their daughter Faith's birthday on Sunday.
Nicole, 52, shared a gushing Instagram tribute to her youngest child as she turned nine, after the family recently flew home to Sydney for Christmas.
'Our baby girl is now 9! We love you so much precious precious girl. Happy birthday Faith!' wrote Nicole next to a picture of Faith's personalised cake.
The Big Little Lies star and rocker husband Keith first welcomed daughter Sunday Rose, 11, in 2008, after the couple initially met at an event in 2005.
During Nicole's previous 11-year marriage to Tom Cruise, the former couple adopted two children together, before splitting in 2001.
The two children made their acting debut in the second season of Big Little Lies, playing extras in two school scenes on the hit show.
Nicole discussed their cameo on Good Morning America at the time.
'There's something wonderful about bringing your children to work and them seeing what you do and them being a part of it,' she gushed.
Nicole's co-star Zoe Kravitz went on to reveal the girls often joined Nicole on set.
'They're around a lot and I sometimes can't tell when they're actually in a scene or just hanging out,' she joked.
