Heidi Klum Impresses In Skimpy Pool Bikini After 'Weight Gain'

Heidi Klum is turning heads in a new bikini look as she promotes Calzedonia on Instagram. The supermodel, 52, thrilled fans with her latest campaign for the swimwear brand, posing in shallow pool waters while flaunting her incredible figure.

Heidi has been making bikini headlines for weeks as she ramps up promo for the stockings and swimwear label on her social media, but some of her posts have sparked body-shaming remarks.

Earlier this summer, users alleged that the America's Got Talent judge has gained weight, although she looked very slender in this video. Heidi doesn't always disable comments on her IG, but she did for this share.

Scroll for the video. Enjoying a swanky infinity pool overlooking the city and palm skylines, Heidi looked every inch the bombshell as she walked slowly toward the camera.

Rocking the upside-down bikini trend in a multicolored, patterned bathing suit with metallic gold straps that included criss-cross chest ones, the former Victoria's Secret Angel dropped jaws with her long legs and killer waistline, also flashing her cleavage while going fairly cut out at the chest.

Looking better than ever, Heidi wore her light hair down, delivering a sultry, come-hither gaze as she shot the lens a direct stare.

Heidi added matte makeup, opting out of any accessories, and showed off her age-defying skin, which appeared to have zero wrinkles. "Summer in @calzedonia," she wrote, adding a #ad. Calzedonia is also fronted by fellow supermodel Kendall Jenner.

The video follows a wave of shaming Heidi Klum was subjected to as she debuted her Calzedonia campaigns over the past weeks. In early June, the catwalk queen posed in a satin bikini from the brand, quickly seeing her post covered by The Daily Mail. While some fans praised the blonde, others turned to body-shaming. "She looks chunky in these pics. I do not mean f-t or overweight, but middle age is upon her," was a comment gaining over 20 likes.

Another shaming remark came from the user, who said that Heidi Klum was "getting a bit thick."

Fortunately, positive replies were also left. "She is looking great and has a figure that I would aspire to. I just absolutely detest these horrid silicone bodies!" One fan said.

Heidi's Calzedonia ads have, however, sparked plenty of Photoshop allegations as fans beg to see something real.

Also sending love was the user replying: "She looks gorgeous. I like that she's smiling and not looking miserable like most models."

Heidi has, elsewhere, made headlines for her attendance at Fashion Week. In the above Instagram photo, she showed off her mile-long legs in a structured, fitted black mini dress. In a caption, she shouted out Lady Gaga's adored designer, Christian Siriano.
