"Like It's Her Birthday" is a song by American pop punk band Good Charlotte from their fifth studio album, Cardiology (2010).

It does not shy away from the dance-y, mall-pop type of music that they were trying to avoid, but it is a catchy single that lets the public know that Good Charlotte is back,"[4] adding, "It will be a guilty pleasure that some will try to ignore, but most will succumb to.

[3] Jon Dolan from Rolling Stone said: "Like It's Her Birthday" sets a man's problem ("She said she only had a meeting/But she is dressed for something/Something that is no good") to a bubblegum groove that a 14-year-old could throw a fist to.

"[8] Eric Sundermann from Spin gave it a positive review, saying: "The track blends a combination of old and new Good Charlotte: It's a fast paced party song, but rather than "The Anthem"-style distorted electric guitars, the group uses synthesizers to create the upbeat sound.

[6] Cameo appearances are made by The Maine's John O'Callaghan and Kennedy Brock, Boys Like Girls' Martin Johnson and Paul DiGiovanni, and Mest's Tony Lovato.
