Martha Stewart on “Watch What Happens Live”; the domestic goddess is refurbishing her image lately.

 Martha Stewart is no Paula Deen. Instead of buttering up her foods, Stewart’s been slowly buttering up the public, introducing a new side of herself that’s light and friendly.

A source tells Confidenti@l that over the past four months, the domestic diva has made a conscious effort to wear shorter skirts and say funnier things in an attempt to show people that it’s not just her oven that gets warm — and she’s enlisting the help of Bravo’s Andy Cohen to help with the makeover.

We’re told in early June, when Stewart, 71, held a talk at the 92nd Y in New York, she had one request — that Cohen ask the questions.

“This is Martha’s big comeback, and she wants to show a whole new side of herself,” a Bravo insider says about the relationship brewing between Stewart and the network. “She doesn’t want a talk show, she wants to show the real her. Something like ‘The Wonderful World of Martha’ is what she’s looking for.”

At that interview, Cohen got Stewart to play “Shag, Marry, Kill,” a naughty game where you have to choose whether you sleep with, marry, or off a celebrity. After he suggested Donald Trump, Mike Bloomberg and Bill Gates, Stewart laughed.

“Trump kill. Bloomberg marry, definitely. And I would do Gates,” she replied.

She also admitted that she has sexted. When asked if she had ever had a threesome, she replied, “Maybe.”

Our source adds that in May, after Stewart had posted a personal ad on the dating site Match.com, she realized how much positive feedback she got just by opening up and showing she had a softer side.

“She’s trying to reinvent herself and realizes maybe the new Martha can appear approachable,” the source said. “Bethenny (Frankel) for 10 years had been chasing Martha and now Martha sees that reality TV can make you successful.” Frankel has said that she modeled her career after Stewart’s.

The source adds that off camera Stewart can be “hilarious.”

“There’s a sassy side to her. Her favorite phrase when she doesn’t like something is, ‘That’s disgusting.’”

Bravo, with Cohen’s help, has churned out star after star and he’s hoping to make Stewart over into a fuzzy personality on a reality-like show that delves into her personal life in a way we’ve never seen.

“He loves legends and strong women, if he can rope in Martha with a hit project it only helps him,” says our insider.

The duo’s relationship is tighter than ever. Wednesday, Stewart appeared on Cohen’s chat show, “Watch What Happens Live” and even loosened up enough to spank him on his butt with a paddle.

Stewart’s last attempt at TV was her daytime show, “The Martha Stewart Show” which was canceled in April 2012.

“Her studio on 26th St. was magnificent but the show was rigid and boring,” says our source. “She doesn’t want to be that anymore.”
