He's got those rocker genes! Gwen Stefani and Gavin Rossdale's son Apollo, 2, can belt out a tune like his famous parents. The No Doubt frontwoman shared a video of their little boy singing via Snapchat on Thursday, May 19.

Stefani, 46, captured the sweet moment while rehearsing for her upcoming This Is What the Truth Feels Like tour. "What are you gonna sing?" someone can be heard asking Apollo in the background.

It didn't take long for Apollo to decide. The adorable toddler then started to sing "Old MacDonald Had a Farm (ee-i-ee-i-o)." Afterward, he walked around hitting drumsticks together — all while sucking on a pacifier.

Stefani and Rossdale, 50, who ended their 13-year marriage last summer, are also parents to sons Kingston, 9, and Zuma, 7. At the time, Us Weekly exclusively revealed that Rossdale was cheating on Stefani with their children's nanny Mindy Mann. Mann is now pregnant and expecting her first child with her boyfriend Spencer Gutcheon.

Stefani appears to be happier than ever since the split. As exclusively reported, her new boyfriend, Blake Shelton, is even ready to propose after just a few months of dating.
