Heidi Klum sparks backlash for faking pregnancy by wearing prosthetic baby bump ... trends now

Supermodel Heidi Klum is coming under fire with some of her 10.7 million Instagram followers for elaborately faking a pregnancy on April Fools' Day. 

After posing for several photos with her fellow America's Got Talent judges while wearing a prosthetic baby bump, the 49-year-old Making the Cut host was met with immediate backlash for her prank that was dubbed as 'tasteless' and insensitive.

On Saturday, the mom-of-four reposted an image, first shared by Sofia Vergara, who could be seen kissing her phony belly, with the caption: 'I'm going to be an aunt!!' 

In the picture, the former Victoria's Secret Angel cradled her stomach in a dressing room as she wore a cropped black sweater, long skirt and a pair of tan UGG slippers.

Howie Mandel also attempted to fool his fans with the picture, which he captioned: 'Congratulations. @heidiklum Co-workers @sofiavergara and I are the first know.'

Hours later, Klum confirmed she was not actually pregnant by posting an image of Mandel, 67, wearing the prosthetic baby bump on his stomach. 

'From me to you CONGRATULATIONS,' she joked. 

The gag was panned by all their followers, with many commenting that 'being pregnant isn't a funny April Fools' joke' since 'so many women suffer from infertility.'

'I find this extremely distasteful and hurtful to those women still going through their  infertility journey,' another wrote.

Dozens of others said the cast should be 'ashamed' of themselves for the trick. 

Others predicted that Klum would have to 'apologize to everyone that's offended tomorrow.' 

Klum's fake pregnancy announcement, however, seemed obvious to many that saw snaps of her in a midriff-baring gown to the iHeartRadio Music Awards last week.

The idea of her expecting is not so far-fetched, though, considering she recently spoke about possibly wanting to have a child with her husband, Tom Kaulitz.
