Wonder Years icon, 48, looks unrecognizable in just a bra as she shows off 6-pack abs 35 years after show
THE WONDER Years star Danica McKellar has shocked fans with her nearly unrecognizable appearance in new photos showing off her fit figure.
The 48-year-old actress took to Instagram last week to flaunt her toned physique while hitting the gym on vacation.
In one close-up shot, Danica smiled following a sweaty workout session donning a bra, no makeup, and her hair in a messy bun.
It followed with more snaps from her exercise routine, where she showcased her toned abs and arms.
She posed with her 12-year-old son, Draco, capturing a full-body shot of her body and workout attire.
Danica paired her black and gray sports bra with tight red leggings, sneakers, and her dark locks flowing straight down.

Her son and husband, Scott Sveslosky, even joined her at one point, with Draco trying out his moves on a boxing bag while his stepdad held it steady.
Danica shares the pre-teen with her ex-husband, Mike Verta.
The family was vacationing in Costa Rica, but that didn't prevent the Dancing With the Stars alum from keeping up with her fitness routine.
She gushed in her caption: "#FBF to working out... on vacation! Costa Rica was great but SO hot & humid, and the ocean & pool were also super warm... so some days we feel pretty sluggish, wanting to just sorta lie around.

"But my body got so antsy & knew it needed to MOVE, so the air-conditioned gym was such a blessing! And man oh man - always SO happy after a workout. That circulation moving, the endorphins flowing."
Danica's post concluded: "Somebody please tell me: Why is it often so hard to motivate to do something that we KNOW we'll be so glad that we did??"
Fans were taken aback by the TV icon's appearance in the snaps and said so in the comments.
"Muscle Mama," one person remarked with a slew of flexed bicep emojis.
"So pretty w/wo makeup," added another.
HOT MAMA
Danica again showed off her pin-thin frame in other photos from the getaway of her wearing a skimpy leopard-print bikini.
Fred Savage's former co-star looked ageless in the Instagram post while posing near a waterfall.
She captioned it: "Costa Rica photo dump!! My family and I had a wonderful time and many adventures!
"Swimming, snorkelling, waterfalls, horseback rides, rainforest walks (that tree frog looks like a National Geographic - but that was taken on my phone!), and more.'
"And that very last shot at the waterfall?
"Shout-out to @glebsavchenkoofficial for teaching me dance arms - if you wanna get better at something, you practice wherever you are!"
Danica added: "We took some pics & video on my husband's underwater camera so once I get those, there might be a part two.
"Super grateful for the opportunity to make new family memories in a cool new spot, and I'm wishing you a week of making beautiful memories, whether on adventures, or right at home."
