Sherri's "after" photo in the painting was pulled from a recent swimwear shoot she did as part of a campaign with Ashley Graham for Swimsuits For All. Sherri shared a video on Instagram from the shoot earlier this week and seemed to have a blast posing on the beach with fellow models. Despite looking super confident, the 51-year-old admitted that she was a little freaked out by the whole thing.

"This was a particularly scary move for me bc I artfully disguise everything on my body I dont want seen," she wrote. "But I said yes to being in a swimsuit bc I wanted to encourage you to run towards the very things you #fear bc there are amazing #blessings on the other side."

Sherri revealed back in early December that she lost a bunch of weight (30 pounds, to be exact) after going on the keto diet and cutting out sugar. "Getting it in!!!" she captioned a pic of herself looking amazing in skinny jeans, a tank top, and thigh-high boots. "Over 260 days #sugarfree cant begin to describe how #amazing I feel." She added, "This is not a fad-its my life that is at stake. It feels so good to feel #good."

As for the motivation behind her transformation? Sherri regularly credits her son Jeffrey as her inspiration.

"Sometimes you go through stuff and you want to just grab something sweet," she said on The Wendy Williams Show back in July, according to Us Weekly . "Ex-husbands, things like that. And I was doing that and Jeffrey was in the backseat, Wendy, and I was eating something I wasnt supposed to. He said, Mommy, if you die, whos going to be my bodyguard? I said, What are you talking about? Whos going to watch me? And literally I said, Sherri, youve got to do something different."

If doing "something different" means a crazy boost of confidence, count me in.
