Lorde has dismissed reports she's dating Lena Dunham's ex-boyfriend Jack Antonoff, but admits she loves her frequent collaborator.

The fun. and Bleachers musician called it quits with Girls creator and star Lena in January (18), and just days later bloggers and gossips started suggesting he had already moved on to date Lorde, real name Ella Yelich-O'Connor.

He shut down the unfounded speculation in a rare Twitter post addressing his personal life, and now Lorde is speaking out.

"Guys, no!" she told a fan during an Instagram Live session on Thursday (22Feb18).

"Jack and I are not dating, for the last time. But I love him, he's awesome. But we're not dating! Please!"

Lorde's comments come a day after it was reported Antonoff paid a visit to the singer while she was on tour in her native New Zealand. They were recently photographed smiling and hugging as they took a stroll through Auckland, but a source told People.com their antics were strictly platonic.

"There's nothing going on between Ella and Jack," said the insider. "There's not any type of romantic situation. They're just friends."

Meanwhile, sources tell The Blast Lorde's new boyfriend, a man only identified as Justin, was also out with the musicians.

Jack and Lorde became close friends while writing and producing her 2017 album Melodrama together, but when speculation about the true nature of their relationship first surfaced online last month (Jan18), the 33-year-old took to Twitter to insist he was single.

"normally i would never address rumours but i resent having the most important friendships and working relationships in my life reduced to dumb hetero normative gossip," he wrote. "those relationships are deeply important and sacred. with that said, im not seeing anyone (sic)."
