Este Haim's boyfriend dumped her because she has diabetes.
The Haim bassist - who was diagnosed with type 1 diabetes, where the body is unable to produce insulin correctly, when she was 14 years old - had advised her then-partner that there was a chance her future children could also develop the condition, and was stunned when his reaction was to end their relationship.
In an interview with Britain's GQ magazine, Este said: "I had a guy break up with me because I said that there was a possibility that our kid would have diabetes.
"He was like, ‘Then why are we here?’ And I was like, ‘What?!'"
The Haim sisters have been sharing their dating woes on TikTok in honour of their new single 'Relationships', and Alana Haim admitted one story she'd told was worse than she described on the platform, having ignored advice from her siblings and flown from Los Angeles to London for New Year's Eve to meet a mystery musician she'd been dating for a year, only for him to high-five her at midnight and for it to later emerge that he'd been cheating on her.
She said: “I was 20, and I was so in love with this guy in a band. Everyone thinks it’s about another guy and it’s not him, that theory is wrong.”
Discussing flying over to the UK over the festive period, she added: “And then he ghosted me the whole week.
“And then I found out he was cheating on me with his ex… I was devastated. Devastated!”
Alana Haim, 33, also recalled another horror story, which saw her dump her boyfriend after he issued her an ultimatum when she was offered a role in 2021's 'Licorice Pizza', but she has no regrets.
She said: "I had a boyfriend that gave me an ultimatum between doing 'Licorice Pizza' and staying with him.
“I obviously made the right choice ...”
Singer Danielle Haim, 36, split up with the band's co-producer Ariel Rechtshaid in 2022 after nine years together, but she has learned she is more than "okay alone".
She said: "Not only okay, but so happy. Sorry to be that bitch but I’m like, really having a great time being by myself. And now, unless someone’s gonna make me so much more happy, I’m good."
Este announced her engagement to Jonathan Levin in February.
Sharing a selfie on Instagram at the time, she showed off a sparkly diamond ring on her wedding finger, and donned a blue t-shirt that read "I'm taken".
