Sony's confirmed the leaked LittleBigPlanet Karting images from earlier in the week are indeed real.
Confirming the game via its Twitter feed, the platform holder said: "We can confirm that LittleBigPlanet Karting is in fact in development and we look forward to sharing more on the game soon!"
Retailer Future Shop tweeted images of the unannounced PS3 racer - and then removed them - earlier this week, claiming they were showcased at a Destination PlayStation event in the US.
The title is apparently in development for PlayStation 3 (not Vita), with ModNation studio United Front Games rumoured to be at the helm - although that's not confirmed.
Further details are scant, but the shop did also note that the game will be 3D compatible, and will come with a 'Move-compatible wheel' peripheral of some sort.
