G-Eazy and Halsey recorded "a couple of records" with each other just days before their split.
The 29-year-old rapper and the 'Bad at Love' hitmaker went their separate ways earlier this week, and in an interview given last week just days before they announced the news, G-Eazy revealed he and Halsey headed into the studio together to record a couple of songs.
Eazy - whose real name is Gerald Earl Gillum - said: "We were actually in the studio just the other night and we did a couple records. We motivate each other and we're fans of each other's music. And we have a similar kind of perspective, aesthetically, on creating music, so we play off each other well."
The former couple had previously worked together on 2017 track 'Him & I', and Eazy couldn't help but gush over the 23-year-old singer's "brilliant" mind.
Speaking to 'Entertainment Tonight', he added: "She's really brilliant. She's an amazing person. She's so intelligent and so insightful and so understanding, she's a brilliant human."
Halsey - whose real name is Ashley Frangipane - announced on her Instagram story on Tuesday (03.07.18) that the pair had decided to split, as she said they were "taking some time apart".
She wrote: "I normally keep this kind of thing private but provided our public nature I feel I need to inform my fans. G-Eazy and I are taking some time apart. I'm eager to continue the upcoming passage of time dedicating myself to my art and career, and the duration of my tour. I wish him the best. Thanks for respecting our privacy at this time."
The break-up came as a shock to many fans, as only a couple of months ago, Halsey admitted she is "really happy" with her life.
She said: "I'm really happy with my life ... [I'm not] this reckless, devil-may-care, angry person [anymore] ... I really love that girl so much ... but now I'm 23, I bought a house and I do my taxes.
"At first, people were, like, 'This is a publicity stunt.' I was, like, 'Well, I hope to God it isn't, because if he's getting paid, I should be too!'"
