When you finish filming the end of HBO series Girls after four years of ground-breaking success, what do you do?

Well, if you're Lena Dunham you celebrate by getting two tattoos in honour of your two favourite legends, that's what.

Adding to her varied array of inking – that include an illustration from the children's book The Story of Ferdinand and the word 'Staunch' to match her best friend's tattoo – the writer/actress has added two new tattoos to add to her collection.

In a post to Instagram last night, the 30-year-old posted a picture of the tattooed artwork depicting American skateboarder Laura Thornhill Caswell (who at the age of 13 become the first female skater to get a board named after her) which is strategically placed so that the skateboard rests above one of the star's endometriosis scars.

'Very satisfying evening getting my (decade old!) tats touched up by my good friend @rbrtbnhm at Brooklyn Tattoo,' she captioned the image.

'He added this new one, a @langleyfox illustration of living legend @laurathornhillcaswell. Cuz sometimes I really need a reminder that we came here to rip shit up,' she added.

Later that evening, Caswell reposted the image of Dunham's tattoo with the caption 'Speechless'.

The Hillary Clinton campaigner – who also shared the inking process via Instagram Stories – also posted a picture of the second tattoo depicting the sign above the famed Tribeca diner, The Odeon.

'And because I'm an officially deranged daughter of TriBeCa, the Odeon neon sign now lives on my ass for life,' Dunham wrote.

I mean, that's certainly one way to show people you like a restaurant.
