What?! Niall Horan’s having chats with Lena Dunham on Twitter

Now, here's an odd celeb pairing.

Mullingar man Niall Horan has his fair share of celebrity pals – he's hung out with everyone from Selena Gomez to Ariana Grande over the last few months.

But one celebrity we'd never have paired the One Direction star with is writer and actress Lena Dunham, the mastermind behind HBO's Girls.

Turns out we were missing a trick though, as the two have indeed been having the chats on social media. Well, they've had one exchange at least.

Things kicked off when Niall tweeted the official Girls account on Monday to pass on his praise for the "absolutely hilarious" show:

And while Niall seems to be a big fan of Lena's work, we're not sure the feeling is mutual, as her response was definitely a dig at 1D's lyrics.

Posting a screenshot of the tweet to her Instagram, Lena ripped off the lyrics to Perfect, adding in a few key Girls references.

"But if you like having panic attacks up in hotel rooms / And if you like a lot of complex fear stuff around men and sex," she wrote.

"If you like to do the things you’re too ashamed to admit to anyone but your therapist / Then baby, I’m perfect." 

Oh, and the best part? She doesn't even follow him on Twitter, at least not if her screenshot is telling the truth:

Hmmm… wonder if this is Lena's revenge for Harry Styles' d*ckhead treatment to her bestie Taylor Swift?

Either way, there's no reply from Niall as yet. Hopefully he saw the funny side…
