The couple took to their respective social media account to announce the release date of their anticipated collaboration, reported Ace Showbiz.
"#IWantYouToKnow 2/23 @zedd," Gomez wrote on Instagram, captioning the single's multi-colored cover art featuring the painting of her face and Zedd's.
The DJ also shared the same artwork on his Twitter and said, "My new single 'I want you to know' ft. @selenagomez is coming out on feb 23!"
'I Want You to Know' was penned by hitmaker Ryan Tedder. The OneRepublic vocalist made the revelation while attending a pre-Grammys party late last week, saying, "The new Zedd/Selena record that has been buzzing about? That's my song!"
Gomez and Zedd have shot a music video for the song and they recently teased it with some pictures taken on the filming set.
