Heidi Klum Exposed In Cheeky 'Valentine's Night' Bikini From A Swimming Pool

Heidi Klum got extra cheeky in her latest Instagram share, one bringing fans bikini action as she marked Valentine's Day. Posting this weekend, the 51-year-old flaunted her supermodel body from a swimming pool, enjoying a late-night dip as she displayed her incredible figure. Looking incredible in a very revealing two-piece, Heidi kept it thong game strong in her stringy swimwear, quickly raking in likes as she enabled comments (a rare move for her). Heidi may be happily married to husband Tom Kaulitz, but it looks like she isn't above flirting a little with her Instagram followers.

Scroll for the photo. Keeping things artsy with a black-and-white finish, Heidi backed it up, confidently showcasing her curves as she posed thigh-deep from an outdoor pool.

Enjoying her evening pool session, the Intimissi ambassador stripped to a micro bikini, baring her backside and curvy waistline while reminding fans of her mile-long legs. Rocking a slightly textured, velour swimsuit with a halter top, Heidi drew the eye from her toned arms and back to her fabulous behind, also hinting at her cleavage as she stood in semi-profile.

Lifting her hands to her head for a bombshell pose, Heidi ruffled her light hair, wearing her locks down while turning her head to the lens as it snapped her. The German-born star also sported dramatic dark eyeliner, looking fierce as she wrote: "Happy Valentine’s Night Happy Weekend Sending Love."

"You're absolute perfection," one user replied. Heidi is known for usually disabling both numbers of likes and comments on her Instagram. For this post, she kept likes turned off, but fans were able to drop a note.

Heidi kept her daywear look stylish in these street snaps, going heavy on the denim as she flashed her legs in a tight dress. Teaming her knee-length number with heels and a shoulder purse, she grinned for the camera, proving she's always a style queen.

That said, some of Heidi's racier outfits have raised eyebrows, although the mom of four isn't bothered by fan opinions. “I’m not shy about my femininity,” she told The Times last year. “I love dressing up where I have my cleavage showing, wearing miniskirts, high heels, gorgeous stockings — but that doesn’t mean I want to go home with you.”

Heidi Klum fronted media outlets with these paparazzi photos last year, freeing herself in the ocean as she enjoyed a luxurious beach getaway in St. Barts. Exposing her bare chest in only teeny bikini bottoms, she reminded the cameras of her sense of femininity, clearly proving that she's okay to bare nearly all. Heidi has since gone topless again while on vacation with her musician husband.
