Kylie Minogue, Bebe Rexha, and Tove Lo have teased a collaboration.

The trio of pop stars shared a video of them answering the same call from "Mom" as Kylie's voice is heard singing "la la la la la la la la la."

A voice then says: "Hi."

Fans believe the tune is called 'MOM' or 'My Oh My'.

It wouldn't be the first time Kylie, 56, has teamed up with Tove Lo, 36, as she previously added her vocals to her tune 'Really Don't Like U' on her 2019 LP 'Sunshine Kitty'.

In a previous interview with The Sun newspaper, Tove recalled: "I met her once in 2018 and she was like, 'Actually, I would love to work with you.'

"I made a note of, 'OK, next record.'

"It was also about having a song where I felt I could reach out and it would be her vibe.

"That song needs to have a sexy, sweet voice on it.

"I wanted to have an icon on this album.

She added some really cool melodies, and she is so lovely and cool and sweet.

"I could talk about her for two hours."

However, she has never worked with 34-year-old Bebe.

Kylie's latest collaboration with 'Midnight Ride' with Orville Peck.

Meanwhile, the 'La La La' hitmaker - who released the acclaimed LP 'Tension' last year - is said to be writing her autobiography.

The 'Padam Padam' hitmaker has reportedly decided now is the right time to put pen to paper and look back on her life with the help of a ghostwriter after finishing her Las Vegas residency and scooping a Lifetime Achievement award at the BRITs earlier this year, because she is at the "pinnacle" of her career.

A source told The Sun on Sunday newspaper's Bizarre column: “Kylie is at the pinnacle of her career and now feels like the perfect time to write about her life and relive some memories.

“She’ll reveal some new anecdotes and stories and dig out some snaps from her archive.

“She will cover her music, TV and film roles, and of course her love life. The finished product is sure to incite a bidding war among publishers.”

The pop idol - who is currently single - recently signed a deal with Netflix for a fly-on-the wall documentary.
