The song received universal acclaim. IGN gave a positive report stating "Pink keeps the mainstream, highly accessible pop trappings in full effect with "Who Knew," further making her whole visual stance that much more hilarious (the contrast of a punky, bad girl doing slick pop may be "rebellious" to some, but frankly it just seems contrived). Despite the slickness, the song does reveal Ms. Pink to have a wonderfully full and mesmerizing voice and makes the fact that she's a star understandable."{{cite news|title=P!nk - I'm Not Dead - Music Review at IGN |url=http://music.ign.com/articles/700/700279p1.html |access-date=February 7, 2012 |newspaper=IGN |date=April 4, 2006 |url-status=dead |archive-url=https://web.archive.org/web/20080516193020/http://music.ign.com/articles/700/700279p1.html |archive-date=May 16, 2008 }} John Murphy from MusicOMH wrote that the song "is perfect driving, anthemic pop."{{cite news|last=Murphy|first=Jon|title=Pink - I'm Not Dead - album review - musicOMH|url=http://www.musicomh.com/albums/pink_0306.htm|access-date=February 7, 2012|newspaper=musicOMH|date=April 3, 2006|url-status=dead|archive-url=https://web.archive.org/web/20121021055423/http://www.musicomh.com/albums/pink_0306.htm|archive-date=October 21, 2012}} Stylus Magazine said ironically that "It’s “Since U Been Gone” spinning its wheels at half-speed, mutedly wondering where the tune went."{{cite news|title=Pink - I'm Not Dead - Review - Stylus Magazine |url=http://www.stylusmagazine.com/reviews/pink/im-not-dead.htm |access-date=February 7, 2012 |newspaper=Stylus Magazine |url-status=dead |archive-url=https://web.archive.org/web/20120503055349/http://www.stylusmagazine.com/reviews/pink/im-not-dead.htm |archive-date=May 3, 2012 }}

It features Pink wearing a light green dress and a young couple visiting a fairground and going on the rides, and at one point the boy puts a necklace on the girl. The video flashes back to the boy secretly injecting himself with drugs on a previous night while the girl is sleeping. At the carnival, when the girl is playing a game, the boy walks away. The girl realizes he's gone and follows him, but when she tries to get him to stay with her he gets violent. He goes to the back of the fairground to inject himself with drugs and breaks into a sweat. His girlfriend wanders around looking for him, and finds him unconscious; he has overdosed. She gives him a kiss, gives back the necklace and phones for an ambulance; after it has arrived, she walks away crying. The final scenes depict flashback sequences showing the couple on several carnival rides together and both Pink and the lovers submerged underwater.
