Ireland Baldwin turns 17 this Thursday, Oct. 25 -- and her famous mom Kim Basinger can't get over how her little girl is growing up!
On a mother-daughter getaway in Hawaii, the Oscar-winning actress, 58, hit the beach with her only child with ex-husband Alec Baldwin. While Basinger (who famously bared all in 9 1/2 Weeks) stayed covered up in sweats, her daughter -- looking more and more like her stunning blonde mom -- showed off her figure in a pink bikini top and black bikini bottoms.
With her iPhone camera at the ready, Basinger made sure to capture the fun vacation moment, taking snaps of her daughter frolicking on the sand and surf -- and even doing cartwheels!
Praising her famous parents to Page Six Magazine in September, Ireland said her mom and dad, 54, "worked hard and are inspirational to me. I never want anything handed to me."
Divorcing Basinger back in 2002 after nine years of marriage, 30 Rock actor Baldwin remarried this past June to NYC yoga instructor Hilaria Thomas.
"I've always had a great relationship with my dad," Ireland said, "And Hilaria and I are really close. She's like a big sister to me, but I feel like I haven't spent enough time with her yet," she said of her stepmom, 28. "I respect her, it's not like I'm Parent Trap-ping her, setting up booby traps in her room."
Her teen cousin Alaia Baldwin (whose dad is Stephen Baldwin) also told the mag: "No matter how much you think you understand a Baldwin, you really don't unless you are one. Ireland and I are pretty sane for Baldwins."
