It’s hardly shocking to see a boldfaced name out East during the summer. But one sighting took a spy by surprise.

“Strange but true. Just saw Anthony Weiner at a children’s park in Sag Harbor with his kid,” said a source. “I noticed him before he put his mask on,” they added.

Of course, Weiner is a registered sex offender, having done time for sending explicit pictures to a 15-year-old in 2016.

Page Six reported earlier this year that parents at his son’s downtown school were up in arms because Weiner was lobbying to be allowed onto the school grounds. He had previously been allowed only as far as the school gates.

Weiner declined to comment.
