The naked swimming baby from the cover of the groundbreaking Nirvana album “Nevermind” re-enacted the image for the record’s 25th anniversary — this time wearing clothes.

Spencer Elden, 25, wanted to go au naturel when he made a splash to honor the legendary grunge band, he told The Post.

“I said to the photographer, ‘Let’s do it naked.’ But he thought that would be weird, so I wore my swim shorts,” said Elden, an artist from LA.

The album, released 25 years ago Saturday, includes songs like “Smells Like Teen Spirit” and “Come as You Are” and has sold more than 30 million copies worldwide.

“The anniversary means something to me. It’s strange that I did this for five minutes when I was 4 months old and it became this really iconic image,” he said.

“It’s cool but weird to be part of something so important that I don’t even remember,” said Elden, who prefers the punk band The Clash over Nirvana.

In 1991, photographer Kirk Weddle asked Elden’s parents if he could use the baby for a photoshoot for the then-unknown band, according to Time magazine. A fish hook with a dollar bill was later added digitally to the image.

The shoot lasted 15 seconds and Elden’s parents made only $200, his dad told NPR in 2008.

Earlier this month, photographer John Chapple paid him $200 to do it again, he told The Post.

Elden hopped in a lap pool at The Rose Bowl Aquatics Center in Pasadena to recreate the album cover image.

Elden did the same thing 10 years ago, in honor of the album’s 15th anniversary.
