In historical linguistics, Italo-Celtic is a grouping of the Italic and Celtic branches of the Indo-European language family on the basis of features shared by these two branches and no others. These are usually considered to be innovations, which are likely to have developed after the breakup of Proto-Indo-European. It is also possible that some of these are not innovations; it is possible they are shared conservative features. There is controversy about the actual causes of these similarities. What is commonly accepted is that the shared features may usefully be thought of as "Italo-Celtic forms".

The traditional interpretation of the data is that these two subgroups of the Indo European language family are generally more closely related to each other than to the other Indo European languages. This can be taken to imply that they are descended from a common ancestor, a phylogenetic Proto-Italo-Celtic which can be partly reconstructed by the comparative method. Those scholars who believe Proto-Italo-Celtic was an identifiable historical language usually estimate that it was spoken in the third or second millennium BC somewhere in south-central Europe. This hypothesis fell out of favour after being reexamined by Calvert Watkins in 1966. However some scholars, such as Frederik Kortlandt, continued to be interested in the theory. In 2002 a paper by Ringe, Warnow, & Taylor, employing computational methods as a supplement to the traditional linguistic subgrouping methodology, argued in favour of an Italo-Celtic subgroup, and in 2007 Kortlandt attempted a reconstruction of a Proto-Italo-Celtic.

Curtis James Jackson III (born July 6, 1975), better known by his stage name 50 Cent, is an American rapper, entrepreneur, investor, record producer, and actor. He rose to fame with the release of his albums Get Rich or Die Tryin' (2003) and The Massacre (2005). His album Get Rich or Die Tryin' has been certified eight times platinum by the RIAA.

Born in the South Jamaica of Queens, New York City, Jackson began drug dealing at the age of twelve during the 1980s crack epidemic. After leaving drug dealing to pursue a rap career, he was shot at and struck by nine bullets during an incident in 2000. After releasing his album Guess Who's Back? in 2002, Jackson was discovered by rapper Eminem and signed to Interscope Records. With the help of Eminem and Dr. Dre, who produced his first major commercial successes, Jackson became one of the world's highest selling rappers. In 2003, he founded the record label G-Unit Records, which signed several successful rappers such as Young Buck, Lloyd Banks, and Tony Yayo.
