omg! Insider is an American entertainment news program covering events and celebrities. It debuted on September 13, 2004 as a spinoff of Entertainment Tonight and started as a popular segment that took viewers "behind closed doors" and gave them "inside" information. Since becoming a separate program, it took a tabloid direction, and has gone through several formats since its 2004 premiere, though since the start of the 2011-12 season it has lost many of the tabloid elements and become more of a straight rundown of entertainment news.

The original theme song was performed by Richie Sambora.

On January 7, 2013, The Insider changed its name to omg! Insider.
