Lena Dunham's ex, musician Jack Antonoff, has publicly brushed off rumours he is dating singer Lorde, calling the talk "dumb heteronormative gossip".
"I resent having the most important friendships and working relationships in my life reduced to dumb heteronormative gossip," the Bleachers singer wrote on Twitter.
The New York based singer, songwriter and producer worked with the New Zealand pop star on her 2017 Grammy nominated album, Melodrama, on which they wrote ten songs together.
Lorde has since retweeted Antonoff's full dismissal of the rumours.

The rare moment of public dialogue on his private life follows last week's split with Girls creator Dunham. Described as "mutual", the couple had been dating since 2012: recently celebrating their five-and-a-half-year anniversary.
Having worked with such powerhouse music makers as Taylor Swift, Banks, St. VIncent and Sia, it didn't take long for rumours of a new love interest for Antonoff to bubble to the surface.
Gossip columnist and blogger, Perez Hilton, circulated that this mystery person was no other than Lorde (with a quick mention of Taylor Swift to keep things juicy). Vogue also pointed out the amount of time the two spent time working together - because we all know ye olde equation: work (man + woman) = sex.
happy birthday to one of the best. so happy to know you and annoy you daily and so thankful to be in a long creative conversation with you about what it means to be alive. ours is a relationship that will be special and vital for a long time i'm thinking. so many memories all over the world in studios and restaurants and at concerts, laughing, crying (me), drinking all of the juices and occasionally disgusting you by walking barefoot through brooklyn.. you make a killer soft boiled egg and you're so fucking patient and i love all of your weird outfit/haircut/beard phases!!!! (i have some very grim photos but only posted the cute ones except for this face swap which is literally the worst thing i've ever seen) you're the top. and so proud that today you have released the first song from an excellent album. JA + EYO forever and always
But in his tweet, the relationship - or, indeed, any other - has been shut down by Antonoff.
"I'm not seeing anyone," he wrote. "Lol."
