Jessica Simpson celebrated her 46th birthday in a polka-dot bikini

Spotted: Jessica Simpson celebrating her birthday in style.

The singer shared an Instagram selfie Wednesday clad in a polka-dot bikini, captioning the post, “💫46💫 July 10/26.”

Along with the tiny two-piece, Simpson wore a chunky gold bracelet, layered turquoise necklaces and sleek wire-rimmed sunglasses.

Though comments are turned off on the post, it’s already amassed almost 21,500 likes in less than half a day.

Simpson shared a few other swimsuit pics last month to promote her collaboration with Walmart.

“Summertime vibes,” she captioned the post, which saw her striking poses in a floral zebra-print maillot and a printed bikini layered beneath a crocheted cover-up.

In April, the singer addressed rumors of her “million-dollar beauty routine,” shooting down claims she once spent $1,000 a week on tanning.

“No, $1,000? Gosh. I’d rather have lain out in the sun,” she told Elle, adding that the story probably originated while she was playing Daisy Duke in “The Dukes of Hazzard.”

“I had to be tan and that was a four-month shoot where I was damn near naked the whole time. The only way to be confident then when shooting was to spray it, and do body makeup. But I also didn’t want it to be too orange, so I had to have a base tan,” she recalled.

“I’ve never been that person who is terrified to be out in the sun because of wrinkles. It just happens and is a part of life.”
