We don't know if little Isaiah got his birthday wish, but the internet sure got theirs when Carrie Underwood [3] serenaded her now-4-year-old son after sucking helium.
In an Instagram video posted by Carrie's husband Mike Fisher, she sucked the gas right out of a yellow balloon – while holding newborn baby Jacob casually in her other arm because she's a multitasking mama – before singing the classic song to her giggling kiddo.
Proof that she's amazing? The Grammy-winning singer even added a chipmunk-esque vibrato to the final notes that proved no one will ever sound that good on helium.
