Kate Hudson and Son Ryder Rap Along to Fetty Wap & It's Amazing -- Watch the Vid!

Kate Hudson is pretty much the coolest mom ever.
During a bored spell at an airport, the 36-year-old actress and her son Ryder, 11, started dancing and rapping along with Fetty Wap's song "Trap Queen." Thankfully for us, Hudson recorded their spontaneous sing-a-long.

The best part of all may have been Hudson's hashtag, #WhenYourPreTeenWantsHisOwnInstagramAndYoureLikeNoooooooo.
The day before, the doting mom posted the sweetest Instagram of her feet intertwined with Ryder and 4-year-old son Bingham's legs.
How lucky are those boys?
Posting energetic, wish-you-were-here videos is kind of Hudson's thing. Earlier in the week, she shared a clip of her and a friend bouncing along to Snoop Dogg while driving.
And on the Fourth of July, she geared up for a patriotic day by singing the "Star-Spangled Banner" while clutching a cup of coffee.

Music is clearly in this hot mama's blood!
The actress isn't just a good singer but a style star, too. See her rock the off-the-shoulder look in the video below.
