They've been together for nearly six years.

And Lena Dunham believed her boyfriend Jack Antonoff was ready to take things to the next level when she thought she overheard him talking about getting her an engagement ring with his sister, Rachel.

Though it turns out the whole thing was just a giant misunderstanding - Jack later confessed to Lena, 31, that what she had actually overheard was him 'talking sh**' about her.

'I thought Jack was furtively planning a proposal (ring emoji) to me with his sister and he just admitted I actually caught him 'talking sh**' about me!', she said in a series of tweets describing the hilarious misunderstanding on Wednesday.

But Lena assured fans there were no hard feelings, adding she was still laughing about the incident.

'Now I literally can't sleep cuz I'm laughing too hard and I am also keeping him awake. 5.5 years, no rock and you know what? It's real nice.'

'Also they were huddled and I heard him say "Lena" and "finger" so obviously it seemed like an engagement ring talk.'

Though, Lena did clarify that she would want newly engaged Cardi B's lavish diamond ring.

'Anyway I want Cardi B's ring,' she finished.

Lena and Jack - who is the lead singer of the band Fun - have famously said that they would get married once gay marriage was legalised.

But joking on Ellen's show in 2015, Lena explained that once gay marriage was made legal, the heat was on her to keep her side of the deal.

She told the host: 'We were thrilled, we were celebrating. And then suddenly the texts just started coming from our friends, from our mothers, from our exercise instructors. Being like finally it’s your time. And we kind of looked at each other we were like, "oh God what have we done?"'

She continued: 'We were hiding behind fake liberal ideals! No we, marrying, we were like those were our beliefs, but then we were like we’re not gonna suddenly just get engaged because it became legal we better wait for a moment where we feel excited about this and I’m excited to marry him at some point, but it felt like a lot of pressure to just go for it that day.

'I did start to ask are there a lot of heterosexuals using this as an excuse to avoid commitment.' she added.

The Not That Kind Of Girl author explained that she already feels committed to her beau.

She said: 'Because I mean we own a dog together. We own a home together, but the marriage thing is a big deal.

'And I also have to say I feel intimidated because I don’t want to espouse any stereotypes, but gay people are kind of killing it at weddings right now they’re kind of winning at weddings. So I don’t want to go in and kind of pale in comparison.'
