"The Voice" Season 23 premiere on March 6 will mark the beginning of the end for Blake Shelton — the only coach of "The Voice" to serve on the panel for every season so far. There’s no doubt the singing competition has been a huge part of the country singer’s life, as he’s filmed two seasons nearly every year since its 2011 debut and even met his wife Gwen Stefani on the show, so there are sure to be emotional times to come for the cowboy. Shelton revealed one moment he’s already experienced that really hit him over the head with the fact that this is his last rodeo.
