This is possibly the cutest singing toddler video ever uploaded to YouTube!
Proud dad Christian Diego Mello from Brazil posted the footage of him and his toddler son singing along to the Beatles' Don't Let Me Down, complete with some impressive guitar action!
The little boy - who is just one year and 11-months-old - joins in enthusiastically with the chorus of the classic tune, strumming his instrument as he does so.
Isn't he the cutest weeny-warbler ever?
