Age is just a number, baby. At least, it is when you’re looking at Kourtney Kardashian. The 39-year-old took to social media on April 11 to share a new bikini photo with fans and followers, you know, just in case you forgot the hotness level she’s workin’ with here.

“Hei,” she simply captioned the super sexy shot of herself enjoying a hot tub in the middle of a snowy tundra on Instagram. The eldest Kar-Jenner sis turns 40 on April 18, but in all honesty, she barely looks a day over 21. And trust us when we say, she’s always looking to flaunt it. She even geotagged the pic, and according to IG’s coordinates, the KUWTK star is currently in Finland — and clearly enjoying the hell out of it. Hey, we would too if we looked like we stopped aging in our teen years.

In an adorable birthday tribute released by E!, Kourt’s 6-year-old daughter, Penelope Disick, even remarked on her mama’s look of eternal youth. “Happy birthday, Mom! Happy 40th,” ex and baby daddy Scott Disick congratulated Kourt on her milestone birthday coming up. “We wish you another happy 40 to come. Keep up the good work.”

In the background of the vid, the little fashionista can be heard saying, “She looks like a kid,” about her mama, which made Scott remark, “And you look very young, [Penelope] says.” Penelope even took it a step further and observed, “You look like a 1-year-old.” LOL. She might be just a bit older than that, P, but you’re not too far off.

Scott, 35, is never one to squander an opportunity for a joke, but ultimately, he just wanted his baby mama to know how much their whole family values her. “We love you so much. We appreciate everything you do and do for us,” he continued as he sat with the former couple‘s eldest son, Mason Disick. “You are a wonderful, wonderful mom … Everything is awesome about you, Mom.”

Yep, including that bod.
