Wonder Years actress looks unrecognizable in a bikini 30 years after starring on the hit show – but can YOU guess who she is?

A star appeared unrecognizable in a recent snap when she shared an image on her Instagram.

The actress looked sensational as she grinned from ear to ear and posed in a leopard print bikini.

Her long, dark locks fell over her shoulders and she wore a pair of oversized shades.

One clue is that the woman in the photo was a child star who appeared in an American sitcom.

Sensational: Danica McKellar made the rare move to pose in a leopard print bikini for Instagram during a family vacation to Costa Rica

She has since voiced Miss Martian in the animated superhero series Young Justice and went on to become a math writer and education lawyer.

For anyone who has yet to work it out, the bombshell is Danica McKellar, 35 years after she appeared on the American sitcom The Wonder Years.

Danica, now 48, who played girl-next-door Winnie Cooper on the hit show, showed off her toned figure as she posed by a waterfall on a family trip to Costa Rica.

The 1990s actress once preferred a side ponytail, with bangs and scrunched hair.

She has been on holiday in Costa Rica with her family and has been able to see the beautiful location with all its beautiful flora and fauna.

Costa Rica photo dump!! ✈️,” she wrote in her caption.

‘My family and I had a great time and many adventures!

“Swimming, snorkeling, waterfalls, horseback riding, rainforest hiking (that tree frog looks like a National Geographic—but it was taken on my phone!), and more.”

Fame: Danica famously played the role of Winnie Cooper in the coming-of-age series, The Wonder Years, which also starred Fred Savage as the main character Kevin Arnold;  the couple in the picture

“And that very last shot at the waterfall?

“Shout out to @glebsavchenkoofficial for teaching me dance arms – if you want to get better at something, practice wherever you are!”

Danica played Winnie Cooper from the age of 13 on the television series from 1988 to 1993 and from 2010 to 2022.

She was the love interest of lovesick Kevin – played by Fred Savage – in all six series and teenage girls who grew up on the iconic series wanted to be her.

She is married to attorney Scott Sveslosky and has an eight-year-old son, Draco, from a previous marriage.

Instead of continuing to act in Hollywood, Danica attended UCLA University and now writes math books with titles like: Math Doesn’t Suck. Kiss my math and girls get curves: geometry takes shape.
