Paul Rudd's cameo in a fan's music video involves Taylor Swift and a song named after him

Taylor Swift unwittingly helped Paul Rudd land his latest role as a loveless, bumbling mailman.

His cameo in the music video for "A Good Thing" came about when the artist, Claud Mintz — who goes by Claud — met him at Swift's The Eras Tour earlier this year.

"I, like, randomly met him in passing at the Eras Tour, at the Taylor Swift concert. I walked kind of like past the VIP tent," Claud explained in a TikTok posted July 16. "I was like, 'Paul Rudd, this sounds kind of weird but there's a song on my album. The song's called 'Paul Rudd.' I hope this isn't weird.'"

According to fan accounts, Rudd was at spotted at one of Swift's three concerts at MetLife Stadium in East Rutherford, New Jersey, in May. Phoebe Bridgers was among the show's opening acts, and Claud is signed to Bridgers' label, Saddest Factory Records.

"He was, like, so nice about it and he gave me his email and he was like, 'Send it to me. Like, I'd love to hear your album,'" Claud said.

Claud sent Rudd their album, "Supermodels," and explained that track eight, titled "Paul Rudd," is named after him because "it's me, like, trying to envision myself as, like, this cool, confident, charismatic, lovable character that you play."

That's how Rudd comes across in real life, too, Claud said. But Claud believes they often don't have those same qualities.

Claud adds Rudd told them he "loved the album."

Filming a music video with Paul Rudd was 'the best day of my life'

This opened the door for Claud to invite Rudd to the filming of their music video: "Would you ever consider stopping by?"

He ended up staying for "the whole entire day," Claud said.

"He stayed for, like, five hours and we shot, like, that whole scene and danced outside and it was the best day of my life," they said.

In the video, Rudd is having difficulty delivering mail inside Claud's building when he knocks on the singer's apartment door. He procures a present for Claud, mistakenly believing it's their birthday.

When Claud corrects him, saying the package is a gift from their girlfriend, Rudd responds, "Girlfriend! Wish I had a girlfriend. I just have a ferret."
