I know, I know. You can name every song, album, and tour that your fave has released and headlined. And that's, like, super cool of you. But as you ease and/or struggle your way into retirement, rest assured that the celebs you've loved and idolized over the years have no such worries.
That's thanks in part, of course, to the magic of brand deals. Check out some of those deals you may have forgotten under the cut, but know that they're not all your typical soda advertisements...
Christina Aguilera for Coca-Cola in 2001.
Nicki Minaj for Beats by Dre in 2013.
Britney Spears for the Z100 radio station in 2003.
Beyoncé for Nintendo—specifically the Nintendo DSi system and the video game Rhythm Heaven—in 2009.
Lady Gaga for Google Chrome in 2011.
Mariah Carey for Intel Centrino Duo in 2006.
