It was hard to believe that Heidi's latest photo was taken over a decade after her time on Playboy.
The star made the cover of the NSFW mag when she was just 22, appearing covered in mud and wearing a white bikini as she offered up 'the dirt' on her show The Hills.
'So sad you would sponsor this please don't claim you're Christian I'm tired of people like you giving Gods people a bad name. Truly unbelievable,' wrote one commenter.
'How do you balance this with your message on @PrattPrayers [the couple's devotional account]? Is this the message you want to send?' asked another.

Although she was happy to get down and dirty for Playboy, photographed wriggling around in the mud in a swimsuit, she did not go completely nude.
'I'm very religious. I’m a big Christian girl. I kind of wanted to keep those values a little bit,' she explained to MTV back in the day.
Still, the magazine reportedly paid her $500k for the spread.
While still a bombshell, Heidi prefers to spend her time focusing on family now. She and husband Spencer are parents to two-year-old son Gunner.
