Father-to-be Tom Fletcher has clearly been thinking about what family means to him, long and hard, as he excitedly prepares for the birth of his first child.
And to celebrate this family vibe, he's only gone and posted a super cute video of him singing Love is on the Radio with his baby sister, Carrie Hope.
Our favourite part is at 1.33, where they catch each others eyes and burst into big ol' goofy brother-sister smiles.
The super-sweet siblings look like the bestest of friends in the vid, with Tom playing the guitar and Carrie taking lead vocals against a stark background.
Listening to Carrie, it's easy to see why Tom dubs her "my insanely talented little sister" - she definitely has the X, Y and Z Factor!
We love that the musical twosome swapped t-shirts, promoting each others' work - and we especially loved that, at the end, they cheekily thrust out their chests and pointed at the slogans for all the world of YouTube to see.
It's Way Past My Bedtime, for all those wondering, is the YouTube handle for Carrie. She's actually a pretty famous vocalist in the worlds of the internet.
Anyone hoping for more from the sibling-singers?
