Lady Gaga has teamed up with a number of life-size replica dolls for a live slot on Japanese TV.

As previously reported, the singer's Japan based record label recently oversaw the construction of GagaDolls - figures of the 'ARTPOP' star that play her music when someone's head is placed on its chest.

She has now given some of the models a live outing for Japan's Sukkiri TV as she performed a piano-only version of her track 'Applause'.

The US star tweeted: "Piano Version of APPLAUSE feat. GagaDolls live from Sukkiri Japanese TV."

As previously reported, Gaga recently revealed on Twitter that she would like to duet with Britney Spears.

The 'Toxic' star said in a fan Q&A that she wants to collaborate with Gaga - and it seems the feeling is definitely mutual.

Gaga tweeted in response: "Lets do this b*tch its time."
