Martha Stewart celebrates 85th birthday with hot tub photo

Martha Stewart took a relaxing dip in a hot tub during her 85th birthday getaway to Maine — and her fans are obsessed with her sultry look.

The lifestyle mogul was pictured in a black spaghetti strap swimsuit in the jetted spa, which featured a forest backdrop and was situated alongside an expansive pool.

Stewart wore a neutral makeup palette and styled her hair in a soft flip while giving the camera a sultry expression as she enjoyed the heated water.

“I am going to use this amazing hot tub every single day I am in maine,” she captioned the snapshot on Tuesday. “Invigorating restorative Therapeutic relaxing.”

In the comments thread, followers gushed over Stewart’s glam appearance, with one person writing, “Damn serving face too.”

Another person wrote, “she is the moment,” while a third quipped, “The cheekbones that launched a thousand ships. Helen of Troy eat your heart out.”

A fourth person suggested the domestic diva share another of her famous thirst-trap selfies, writing, “Waiting for the new ‘hot tub selfie’ 💋.”

Still others simply labeled the TV host an “icon,” “goddess,” or “queen” in their comments.

Stewart — long known for her prowess in the kitchen and garden — has also become a fashion and beauty icon in recent years, regularly taking to social media to show off her stunning hair, makeup and style makeovers.

The author isn’t shy about touting her own good qualities, telling Page Six earlier this year that she’s “a very good catch.”

“I know how to cook, I know how to clean, I know how to keep a house; those are all very homemaker skills,” she told us during an event appearance in March.

Stewart added that  “of course” she still dusts, and boasted that she “completely redid a room” that very week.

“I got a new rug, we were moving furniture, it’s spring cleaning time!” she said at the time.

That same month, she jokingly told People that for her part, she likes a man who is “smart,” “funny” and has “nice teeth and a nice smile.” Oh, and money.

“Rich helps,” she laughed. “Very rich helps even more. Plane and yacht would be very nice. … I love yachts.”
