Even free-swingin’ Hollywood is embarrassed by selfie-obsessed Anthony Weiner.

The disgraced ex-politico’s much-touted cameo on the finale of DC-based web series “Alpha House,” which streams on Amazon, is literally five seconds long — with no dialogue.

The former congressman and New York City mayoral hopeful is seen grim-faced — a familiar look he showed to the public during his multiple sexting scandals — entering a memorial service for a fellow politician who died while having sex with his secretary.

Amazon Studios, which produces “Alpha House” — from “Doonesbury” creator Garry Trudeau and starring John Goodman and Mark Consuelos — did a big PR push in leaking word about Weiner’s appearance several days before streaming the episode on Friday.

It’s a wonder why they bothered.
