The 29-year-old Girls actress shared a snap of herself lying fully-clothed on a bed of warm rocks alongside two female friends, jokingly captioning the shot, 'stoners'.

Lena can be seen relaxing during her pampering session, wearing a bold patterned minidress cut to the top of her thighs.

The massage gradually heats up the body and is said to have a detoxification effect, working wonders for both the circulation and the skin.

Ahead of her spa day, Lena shared another picture of herself posing with two pals during her mystery Japanese trip.

Get sporty like Lena in a printed dress by Mary Katrantzou

Lena Dunham has an incredible sense of humor which extends into expressing herself with her quirky sense of style. Here she's spotted in Japan rocking yet another Mary Katrantzou designer dress.

This is a fashion match made in haha heaven. Both love whimsy and while Lena is joking about being a stoner, Mary Katrantzou, will design a dress with stone prints. This is the second time we've spotted Lena in Mary Katrantzou.

This badminton inspired dress is such a fun statement item to wear and since it's a collaboration with Adidas, the price is a very affordable $200. Head over to Barneys now to pick this up or if you're looking for something a little less sport-obvious, we found several unqiue print dresses that will make heads turn.

Pair yours with sneakers for a ultra sporty look or some purple strappy sandals for a night out.

The annual fundraiser - in which Gwyneth Paltrow was also in attendance – saw Lena take part in a paddle board race held at the Hamptons.

The popular star posted a picture of her at sea with the funny caption: 'It's hard to tell from this blurry shot, but this is an image of Laird Hamilton coming to save me.'

She continued: 'He is literally King Triton and as I struggled to complete BCRF's Paddle for Pink (an amazing event to support breast cancer research) he appeared as if from the ocean's depths and guided me to the finish line.'

Later adding: 'I kept screaming "will I make it?!" like we were in a disaster movie. He said "yes, Lena, we will." Ladies, there are still a few heroes we can count on... #ThankYouLaird #paddleforpink #3miles.'
