Heidi Klum Exposes Chest In Wet Braless T-Shirt

Heidi Klum was in the mood for a little throwback action this week. On Friday morning, the 51-year-old shared an old modeling shot from way back in the day, posting a pantless look to her Instagram while reminding everyone how little she's changed over the years. Looking fierce as she flaunted her mile-long legs in only a t-shirt, underpants, and high heels, Heidi flew the flag for the braless trend, also upping the ante as she modeled a shirt that was soaking wet. Thrilling her followers as she classily exposed her bare chest, Heidi gave a nod to the weekend with a caption shouting out "TGIF."

Scroll for the photo. Swinging a hip as she posed from a studio, Heidi drew the eye to her impossibly long legs as she wore a plain white t-shirt that was both transparent and soaking wet. Showing plenty of muscle definition as she wore heeled shoes with corseted criss-cross detailing on the front, the America's Got Talent judge wowed while ditching the bra, completing her minimal look with teeny underpants in black.

Dipping her chin a little, Heidi sent the camera a piercing gaze, wearing a dramatic eyeliner layer and matte makeup as her hair was styled down and drenched. In a caption, the Intimissi ambassador wrote:

"Thank God it’s Friday #TFIG." Heidi has both numbers of likes and comments disabled on her Instagram. Her account has recently been promoting the AGT competition series she stars in, but there's also been some racy action thanks to those skimpy bikini videos and lingerie snaps.

In June, Heidi Klum stripped down to an expensive-looking, semi-sheer undies set in white. Posing on her knees for couch photos as she rocked messy bed hair, the mom of four dropped jaws with her super-toned tummy, showing off her killer curves as she tugged up her stringy, lacy briefs. In a caption, the blonde wrote: "Good morning my love" in Italian.

Heidi is earning cash for her lingerie posts, though, as she continues to front luxury brand Intimissi.

The above photo was shared to 20-year-old daughter Leni Klum's Instagram last year. Heidi Klum and her daughter turned heads in their plunging bra and briefs looks, with the post marking another ad campaign for Intimissi. While Heidi wore pastel purple, Leni stuck to classic white.

"Our new @intimissimiofficial campaign! Find my mom and I on billboards all over Germany and tag us if you see it!! Explore the new collection now online and in all Intimissimi stores," Leni captioned the shot. Fans left over 300,000 likes.
