"No Doubt" singer Gwen Stefani's son Zuma, an aspiring country singer, is a lookalike to stepdad and ex-coach of "The Voice" Blake Shelton.

Gwen Stefani celebrated her son Zuma's birthday with an adorable Instagram carousel — and made sure to highlight his musical talents!

Stefani shares Zuma with her ex-husband, Bush lead singer Gavin Rossdale, whom she married in 2002. The former couple also welcomed two more sons, Kingston (born in 2006) and Apollo (born in 2014), before they filed for divorce in 2015.
