Sigala joked about wondering if Little Mix fans "bugged [his] studio" after they leaked his collaboration with the girl band's former member Leigh-Anne Pinnock.
The 32-year-old DJ-and-record producer worked with the 34-year-old singer on his new track Hello.
Sigala - real name Bruce Fielder - told the Daily Star newspaper's Wired column: "I mean, the Little Mix fan base is just next level, like I don't have anywhere near that kind of fanbase.
"And so working with Leigh-Anne, I've experienced some of that, it's crazy how they find stuff out before.
"I saw posts about it before we'd barely finished doing the day in the studio, it's like they bugged my studio.
"Because even when I barely sent it to anyone, and then suddenly, it's like on social media, and I'm like, 'OK, well, who's the mole here? Like, what's going on?'"
He also revealed that Talia Mar's song Stay the Night could have been a track for Little Mix - originally formed of Leigh-Anne, Jesy Nelson, 34, Perrie Edwards, 32, and 32 year old Jade Thirlwall.
Sigala - has previously worked with Kylie Minogue, 57, RAYE, 27, and 31 year old Becky Hill - explained: "The song Stay the Night that I did with Talia Mar - before Talia did it, it was potentially gonna be Little Mix.
"But I think it was around the time when they had Heartbreak Anthem, which was going crazy, and the timing didn't really work out.
"So the only time where it's obviously tough to navigate is when something happens to the track.
"You then have to go, 'OK, I'm putting the song out, but it's with this different person,' and people get confused."
Hello is a feel-good, genre-splicing tune, and Sigala recently said he, Leigh-Anne and Indian music and film star Jonita came together in an unlikely collaboration to make the song.
He said in a statement: "I'm so excited for the fans to hear what I've been cooking up in the studio these past few months, kicking things off with my new track Hello.
"I love collaborating with other artists, and it feels perfect to have a superstar like Leigh-Anne and one of India’s biggest talents - Jonita on this one with me - we had such a vibe creating this song and working together on the fun visualiser."
Leigh-Anne commented: "It might be an unexpected collaboration, but I think that’s exactly what makes this track so unique.
"We all bring something different to the table, different genres, different vibes, and it just works.
"Working with Sigala and Jonita was such a vibe. I love Jonita’s energy, and hanging out with Sigala throughout the process was fun."
Jonita added: “Hello is such a fun, feel-good song, and I collaborated with Sigala and Leigh-Anne on this track completely remotely, which reminds me that music can bring people together no matter where we come from.
"For me, it’s all about joy and connection, and I’m so grateful I get to contribute a bit of my own personality in something that feels so universal.”
