Hudson spent time in Hawaii with her mother, actress Goldie Hawn, who's currently filming her upcoming action-comedy movie with Amy Schumer in the tropical state. Proving good genes run in the family, 70-year-old Hawn also showed off her incredible beach bod last week, rocking a black one-piece.

The mother-daughter trip basically looked like the best time ever, with Hudson taking some time to relax with a little beach reading.

"First summer read! ALL ABOUT LOVE by Bell Hooks #SoFarSoGood," Hudson captioned a pic on Instagram that showed her book, and highlighted her flat stomach at the same time.

"Aloha #MamaGoldie," she also wrote as her and her famous mom reclined on beach chairs.

Schumer also joined them on their girls getaway, the two jumping off the boat, grilling and getting up close to dolphins.

ET caught up with the mother-daughter duo at Hawn's annual Love In For Kids charity event last month, when Hudson said she was looking forward to visiting her mom and Schumer on set.

"It's kind of a no brainer. I mean, Amy Schumer, my mom," Hudson told ET exclusively. "My mom hasn't worked in a long time for a reason, and I think this is the perfect thing for her to come back… I really look forward to it. I'm so excited. I'm going to go visit them!"
