Heidi Klum In Bikini With 20-Year-Old Daughter Told To 'Cover Up'

Heidi Klum is back on shores just days after she went completely topless for a beach outing including 20-year-old model daughter Leni Klum. The 51-year-old supermodel spent last weekend in Porto Cervo, Italy, enjoying more of her Mediterranean summer getaway, one so far seeing her chased by the paparazzi wherever she goes. On Sunday, Heidi was photographed showing off her stunning figure in a bikini while going water-sledding. The active day also included husband Tom Kaulitz, daughter Leni, plus Leni's boyfriend Aris Rachevsky. While Heidi was praised by some, many threw shade.

Scroll for the photos. Showing off her figure in a skimpy patterned bikini in brown and black, Heidi flaunted her assets and flat stomach while prepping for her water sledding. Wearing floral-print, green shorts with pink rose motifs on them, the Project Runway alum tied a large sarong around herself, going makeup-free and throwing in a pair of shades.

Meanwhile, Leni was seen on a pier as she highlighted her ample curves and long legs in a tiny bikini in purple and pink. The Dior Beauty ambassador added in Ugg boots and shades, slinging a bag over her shoulder.

Heidi eventually stepped out onto the pier, joining Leni on a speedboat. Leni, who jointly fronts lingerie brand Intimissi with her mother, was also seen smooching beau Ares.

The photos were published by The Daily Mail yesterday, and it looks like the reception was lukewarm. Noting Heidi Klum's glossy Instagram photos, the most popular reply read: "So a lot of photoshopping going on when she publishes the photo's herself." Shaming Heidi for stripping down at 51, another said: "Not sure she can still get away with wearing a string bikini."

Appearing to agree, a further fan wrote: "Time for mama to cover up." Here, a user fired back, stating: "Oh really? On the beach? Why? She’s got a better body than many 25-year-olds we see on our local beach…"

Heidi and Leni made May headlines for stripping down to minuscule bikinis at their five-star Cannes hotel. The duo then made glamorous appearances at the Cannes Film Festival, but it looks like they're back to their favorite looks. The above photo dates back to earlier this month, when Heidi and musician husband Tom lounged around with Leni nearby. Of course, Heidi being topless made instant headlines.

Heidi and her family have been in Sardinia, where the above photo of Leni was taken. Stunning in her string bikini, the rising sensation proved she's inherited her mother's genes. Heidi Klum has a reported $160 million net worth.
