Good Genes! Naomi Watts Shares Sweet Pic With Lookalike Mother and Grandmother

The 47-year-old star took to Instagram to share a sweet snapshot with her mother and her grandmother during her recent trip to Australia.

"Great New Year's Eve with Mum and Grandmother. Two very important and special women in my life," she captioned the cute candid, adding the hashtags: "three generations," "lucky" and "my peeps."

Earlier in the day, the mother-of-two got wild at the zoo with husband Liev Schreiber and their sons, Alexander and Samuel.

"Fantastic day meeting the lovely koala and all the other animals," she wrote alongside the fun family photo. "Happy Birthday #100 !!! Thank you for hosting us @TorongaZoo #sydney #zoo."

The "Divergent" star recently talked about her boys, admitted that her life is "pretty much nonstop."

"They love roughhousing with daddy, and they need it, living in a place like New York where you don't have gardens to run around in, but it's not the same," she told Mom.me. "So lots of roughhousing, and you can get really hurt. Head-butting and things going wrong—not on purpose—but there are lots of tears, and so I always say, 'No, no, mummy is a delicate flower, save the roughhousing for daddy!'"

"Luckily I grew up with an older brother, so I've always been more of a tomboy and never much of a prissy girl or delicate flower EVER," she added. "But I'm just a bit old now and my body doesn't work the same way!"

When it comes to disciplining her sons, she splits that role with her hubby. "We're pretty balanced, so Liev and I trade," she explained. "Sometimes you're softer, and next moment you are cracking down. It's about trying to be consistent. There are rules, but they can be broken every now and again. We do believe in disciplining, so there are time-outs and stuff. Sometimes just to keep them still, but it's only when they hurt each other."
