Gwyneth Paltrow is celebrating an upcoming milestone birthday in style.
The actress, 49, shared a black-and-white photograph of herself jumping while wearing a bikini on Instagram Thursday.
In the caption of her post, the Iron Man star wrote, "Musings on a milestone," and directed her followers to a link in her bio to her Goop blog, where she spoke candidly about her thoughts on turning 50 next week.
"A collection of marks and irregularities that dog-ear the chapters. Scarred from oven burns, a finger smashed in a window long ago, the birth of a child. Silver hair and fine lines," she said.

As Paltrow continued that she does "what I can to strive for good health and longevity, to stave off weakening muscles and receding bone," the star then wrote, "I have a mantra I insert into those reckless thoughts that try to derail me: I accept."
"I accept the marks and the loosening skin, the wrinkles. I accept my body and let go of the need to be perfect, look perfect, defy gravity, defy logic, defy humanity," she added. "I accept my humanity."
GOOP Gwyneth Paltrow
Back in October 2021, Paltrow chatted with PEOPLE about aging and how she still struggles with her body image.
"Unfortunately, we're always looking at ourselves with a critical eye," the Goop founder explained at the time. "I would love to get to a place where I don't do that anymore."

She continued, "I want to show up for myself in a more loving way, because it's all going south from here! There's nothing we can do about it."
For Paltrow, who is mom to daughter Apple, 18, and son Moses, 16, with ex Chris Martin, changes in her body became most apparent after she had her first child, though she explained her own acceptance journey has shifted since then.
"For me, as I go through the aging process and really start it, I realize it's less about, 'Oh, I have this wrinkle, am I going to fix it or not?' and more, 'Do I feel vibrant?' " she previously told PEOPLE.
"I would never want to go back to my 20s, or even my 30s for that matter," added the star. "I know myself, I like myself and I am so grateful for the wisdom that comes with age."
