The same night that her ex released "10,000 hours," Gomez took to social media and insisted her 157 million followers download Niall Horan's new song, "Nice To Meet You."
Gomez, who battles Ariana Grande for the most followed female on IG, used her manpower to hawk the former One Directioner's track, instead of Bieber's.
"This came out like 5 min ago... and I'm pretty sure you need to download @niallhoran," she insisted.
Interesting timing, because Bieber released his wedding song featuring Dan + Shay at the exact same time.
Bieber promised fans that the video, which will feature his bride, Hailey, will be released today at 1 PM EST.
The song is all about true love, but it also kind of disses past ones too (like Selena Gomez), with lyrics like: "I been looking out for love. But never really quite found the one. They say practice makes perfect. I know I deserve it."
Gomez and Bieber dated off and on for several years.
They were first linked in 2010 and magically found their way back to each other in 2017 following her split with The Weeknd.
Ironically, the couple nicknamed "Jelena," broke up in the beginning of 2018 and he found his way to Hailey.
Mr. & Mrs. Bieber!
As The Blast reported, Justin and Hailey said "I do" earlier this week for the second time, but this wedding was in front of family and friends.
The duo exchanged vows just one year after secretly tying the knot in an NYC courthouse.
