Earlier this week, Beyoncé released a new remix of J Balvin and Willy William's 'Mi Gente' and vowed to donate all proceeds to disaster victims in Puerto Rico, Mexico, and other Caribbean islands.

The song, and its charitable cause, came as a surprise to fans and music lovers alike. But what's even more surprising is that Bey's daughter, Blue Ivy, apparently also sings on the track.

Beyoncé sings in Spanish for most of her feature on the Latin hit. But if you listen in on the pre-chorus, she says, 'Azul, are you with me?' using the Spanish word for 'Blue'.

After that, a small voice responds, 'Oh yes I am'.

The Bey Hive pointed out the five-year-old's cameo, and Beyoncé fans celebrated on Twitter.

This is far from Blue's first feature.

She's credited on Beyoncé's song 'Blue', which was released when she was just one year old, and she even freestyles on JAY-Z's track, 'Blue's Freestyle/We Family'.

We wouldn't be surprised if Rumi and Sir got their own features when they start speaking, too.

Listen to the 'Mi Gente' remix, featuring Beyoncé (and Blue Ivy) below.
