Edwards and Malik met in 2011 during the eighth season of The X Factor UK. At the time, Little Mix was competing on the series, while Malik's One Direction -- which finished in third place one year earlier -- had returned for a performance. Little Mix would go on to become the first and only group to take the show's top prize.
The couple became engaged in 2013, but split in 2015. (For those fact-checking the lyrics: Yes, that's "four long years to call it quits.")
That same year, Malik also called it quits with One Direction, leaving the band to pursue a solo career. He released a debut solo album, Mind of Mine, in 2016.
Well, it sounds like Edwards surely is "over it" by now. The chorus of Little Mix's new song -- which was penned by the girl group, alongside Camille Purcell, Iain James and Electric -- is all about empowerment.
"Shout out to my ex/You're really quite the man/You made my heart break and that made me who I am," the girls sing together in unison. "Here's to my ex/Hey look at me now/Well I'm all the way up/I swear you'll never bring me down."
"Shout Out to My Ex" will be featured on Little Mix's fourth studio album, Glory Days, due out on Nov. 18. After that, Edwards, Jesy Nelson, Leigh-Ann Pinnock and Jade Thirlwall will join Ariana Grande on her Dangerous Woman North American tour, kicking off Feb. 2 in Phoenix, Arizona.
Just last year, Little Mix was busy promoting their "very colorful" Get Weird album and stopped by ET to chat all about it. Watch below!
