She has made it clear that she doesn't care what people think about her.

And Lena Dunham managed to keep a straight face as she splashed in a pool while displaying her interesting ballet and synchronized swimming moves in a funny Instagram video on Wednesday.

Showing off her figure in a black bikini in the hilarious clip, the actress and producer, 31, wrote alongside the post: 'I am an artist with many mediums.'

Lena exposed her many tattoos while in a revealing black bikini as she performed ballet positions.

The Girls actress wore her short blonde hair tied in a tiny bun on top of her head.

The Instagram video showed the native New Yorker holding her nose as she flopped belly up in the pool, trying to flip over.

Although perhaps not quite as graceful as a typical ballerina or sychronized swimmer, Lena's legs were seen kicking in the air as the actress pulled herself up from out of the water.

After she showcased her aquatic skills, Lena posted an other video to her Instagram story.

In the video, the new American Horror Story actress was accompanied in the pool by her adorable pooch.

The dog-mom shared a sweet moment with her pup as the two swam together in the water.

Besides showing off her creative abilities in the pool, Lena has been busy working on multiple projects.

Last week the feminism activist took time to celebrate the second anniversary for her online magazine, Lenny.

Lenny is a feminist newsletter supported by Heart Publications that consists of content covering politics, fashion, culture, and health.

Just like she enjoys poking fun of herself on social media, Lena revealed she also does that when it comes to fashion decisions on the red carpet.

Last week, the actress revealed to E! News: 'Ending up on that "Good People, Bad Clothes" page or whatever it's called...that stuff gives me pleasure.

'There are a few pictures of me in, like, a weird shift dress and a blowout from early on where I'm like, "I'm not hosting a morning television show!" but I thought there was some [image] that you had to fit into.'

Lena ended: 'Now I understand that it doesn't matter.'
