Little cutie! Gwen Stefani's album promotion is a family affair — and on Thursday, March 17, her 2-year-old son, Apollo, got in on the action.

Filmed in a video while lying in his bed, the little tyke uses his best voice to encourage his mom's fans to log onto the Internet and download her new album, This Is What the Truth Feels Like.

"Everybody go to iTunes," her little tot says to the camera, once his pacifier has been pulled out of his mouth.

"How come?" Stefani asks her son. "Why?" he answers. "Cause Momma's record," she replies.

Stefani didn't really need Apollo's extra sales push, having already celebrated being No. 1 on the charts earlier in the day with a totally over-excited tweet.

#1 on iTunes ? #thisiswhatthetruthfeelslike wow omg #thanku gx

“Omg!!!!! THANK U!! !!!!!!🙏🏻I can’t believe it ????!!!!!!!! Love u,” she wrote, while proud boyfriend Blake Shelton was equally overwhelmed. "I am freaking out!!! Congratulations @gwenstefani!!!!” he tweeted. 

But while Apollo’s message might not have been necessary, his sweet little face was a welcome reward for fans who had already purchased her new album.

Sharing a photograph of the two of them snuggled up in his Star Wars bedding, the mom of three expressed her gratitude to her legions of supporters.

"Thank u everyone who made me #1 on iTunes! #blownaway ThisIsWhatTheTruthFeelsLike gx," she captioned the photo.
