She's never been shy about sharing revealing photos on her social media.

And on Tuesday, Lena Dunham did just that as she flaunted her curvy form in a brightly colored bikini set.

The actress, who also showed off her tattoo on her derriere, gave a front and back view of the swimwear on her Instagram stories.

Not shy: Lena Dunham flaunted her curvy form in a brightly colored bikini set on Tuesday

The 31-year-old's two piece featured a sports-bra style top and high-waisted bottoms.

Lena said of her red and orange set: 'Front view even better? This is the best swimsuit for my curvy bod I've found!'

Adding a shout out to the brand @shophotlava.

She posed facing away from the camera for her second snap as she tagged the brand and its founder, Rachel Finley, who goes by the handle @instasteak.

This isn't the first time Lena has flaunted her uniquely placed orange tattoo.

She revealed the permanent backside ink in October of last year; the star explained the reason behind it on her Instagram post.

Lena's tattoo of The Odeon on her left butt cheek was done by artist Robert Bonhomme - in honor of the famed restaurant in New York City.

It was done in an orange hue - which matched the neon sign of the real life eatery in Tribeca.

Lena captioned it: 'And because I'm a deranged daughter of TriBeCa, the Odeon sign now lives on my a** for life.'

In addition to the unique art, Lena also has a tat on her torso - featuring an illustration by artist Langley Fox of skateboarder Lauren Thornhill Caswell.

The HBO star chose to have the artwork done above her scar from her endometriosis surgery she underwent in March 2016.

Endometriosis is a disease where the lining of the uterus grows outside of the uterus; she was undiagnosed until after the first season of Girls wrapped.

She also has large tattoos beneath her breasts and on her thigh.

Last fall, Lena retouched her arm tattoo, which features a grazing bull peeking out of flowers.

She explained that she got the tattoo 11 years prior and needed to get it 'touched up by my good friend.'

The TV star said on Instagram: 'Ferdinand restored to his original pacifist glory...this was definitely the coolest thing I did at age 19.'

The tattoo was inspired by The Story Of Ferdinand - a children's book about a bull who would rather stop and smell flowers than fight.

She is a big fan of tattoos; Lena also has two houses inked on her upper back, the word 'staunch' on her wrist and Eloise - the children's book character - tatted on her lower back.

She also has a Yorkshire terrier inked on her rib cage - which her Girls co-star Jemima Kirke tattooed.
