After 11 years of waiting, No Doubt finally released their new album Push and Shove this week.

On top of the big release, Gwen Stefani and the band visited the Ellen show, and the gorgeous mom-of-two reveals that parenthood has been the big reason why they waited this long for a new album.

Lucky for her, it may have been worth the wait, as younger son Zuma, 4 seems to have developed an attachment for the guitar.

“Zuma’s the one who’s showing more interest in the guitar,” Stefani explained to DeGeneres. “Since he was tiny, he’s always played guitar–well, he doesn’t really play guitar, but he thinks he does.”

Check out the interview and Zuma’s performance below.
