Yep, it's that time again folks - talk of Christmas adverts has already started.
And this was one we weren't expecting. H&M has announced that Tony Bennett and Lady Gaga will join up to star in its Christmas campaign for 2014.
The two superstars will both appear in the TV campaign, performing a track from their album Cheek to Cheek, which will be released on 23 September 2014.
And is it just us, or is Lady G channelling a little Cher right there? The huge curly black wig, those fishnet tights. She's even got the smouldering eyes and orange lips down.
The upcoming album is a collaboration between these two generation-spanning artists in celebration of jazz music.
And Cheek to Cheek was named after the Fred Astaire and Ginger Rogers' 1935 song that Bennett has also previously recorded.
The new Christmas campaign will make its global TV debut at the end of November, with a longer version running on the H&M website.
Lady Gaga is one busy bee, currently on her artRAVE: ARTPOP Ball Tour.
Back in November 2013, Lady Gaga dipped her toe into the H&M fashion pool by officially opening H&M's Times Square flagship store in New York, with fans and her Little Monsters queuing for the chance to meet and shop with their idol.
Tony Bennett, in his seventh decade as a world-class performer, is a 17-time Grammy winner.
They make an unlikely but pretty cute duo, don't they?
