Lena and Jack broke off their five-year relationship in January this year, with reports coming out that the split was "mutual", according to E!
"Jack and Lena were growing apart and it just made sense for them to end their relationship where it was."
Shortly after, like the same month, Us Weekly was reporting that he and Lorde were officially a thing.
"The relationship is done and he has moved on,” the site reported, “as in he is seeing someone else."
BUT, Jack was quick to deny these rumours, as he helped produce Lorde's album, Melodrama.
"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. those relationships are deeply important and sacred. with that said, im not seeing anyone. lol," he wrote.
Seems like that might have changed though.
As for Lena, she has been in hospital getting a hysterectomy because of her endometriosis. Sharing the news with her fans, she wrote, "In addition to endometrial disease, an odd humplike protrusion and a septum running down the middle, I have retrograde bleeding, a.k.a. my period running in reverse so that my stomach is full of blood."
"My ovary has settled in on the muscles around the sacral nerves in my back that allow us to walk. Let’s please not even talk about my uterine lining.
"The only beautiful detail is that the organ — which is meant to be shaped like a light bulb — was shaped like a heart.
"I may have felt choiceness before, but I know I have choices now," she said.
"Soon I’ll start exploring whether my ovaries, which remain someplace inside me in that vast cavern of organs and scar tissue, have eggs.
"Adoption is a thrilling truth I’ll pursue with all my might."
