Jack Antonoff recently took to Twitter to deny the rumors they're a couple.

And on Thursday, Lorde, 21, repeated that sentiment, telling fans during an Instagram Live session that she and the 33-year-old Fun band member were not together according to DailyMail.

'Guys… Jack and I are not dating, for the last time.'

The Royals hitmaker responded to a question from a fan about her relationship status with the songwriter with a defiant No.

'I love him, he's awesome. But we're not dating! Please!'

Antonoff has a long working relationship with the New Zealand singer, having penned 10 songs for her sophomore release, Melodrama, which was nominated for Grammy for Album Of The Year.

But despite her denial, the music producer certainly seemed to be quite comfortable with cuddling up with the Green Light hitmaker earlier this month.

The guitarist and Lorde - real name Ella Marija Lani Yelich-O'Connor - seemed very tightly knit when he visited the Tennis Court songstress in her hometown of Auckland, New Zealand.

Lorde wrapped her arms around the Fun band member at many points and they even strolled together arm-in-arm during their day on the town.

The outing together came just a month after the musician shot down rumors they were dating.

'Normally I would never address rumors but I resent having the most important friendships and working relationships in my life reduced to dumb hetero normative gossip,' he wrote on Twitter. 'Those relationships are deeply important and sacred.'

He added: 'With that said, I'm not seeing anyone. lol.'

Back in January reps confirmed that Antonoff and Girls creator Lena Dunham had split after five years together.
