She apparently doesn’t think Father knows best.

One of Gov. Andrew Cuomo’s daughters posted a photo on Instagram two days ago showing her and her dad strolling on an Albany street wearing face coverings over their mouths — but her nose was glaringly uncovered, a major no-no among health professionals amid the deadly coronavirus and against what Papa’s been preaching.

“OMG…Cover your nose!” a commenter wrote alongside the photo of Mariah Kennedy Cuomo, 25, and her father.

Another person wrote, “Please everyone, be sure to put the mask over your nose as well as your mouth.”

Mariah had written when posting the snapshot, “Walking Captain with the ‘love gov’” — referring to her single dad’s nickname among women amid his daily coronavirus press briefings.

Gov. Cuomo has become a national poster boy for coronavirus precautions — last week ordering state residents to wear face and nose masks in public.

“If you are going to be in a situation, in public, where you come into contact with other people in a situation that is not socially distanced, you must have a mask or a clothing covering nose and mouth,” he said.

“You don’t have the right to infect me,” Cuomo said.

Also on the father-daughter outing was Gov. Cuomo’s Siberian husky-malamute mix, Captain, who appeared to be held on a leash by Mariah’s boyfriend, Tellef Lundevall. The governor was wearing a dark bandanna over his face, while Lundevall also wore a covering.

A Cuomo rep — asked by The Post on Tuesday about Mariah’s failure to cover her nose — said, “It was a momentary slip of the mask.”

The governor, who frequently gets personal during his media appearances over the virus, talked Monday about a recent family dinner with his three daughters, at which Lundevall was present.

“The answer on what you think of the boyfriend is always, ‘I like the boyfriend,’ ” Cuomo said.
