Lady Gaga and Tony Bennett's full H&M Christmas campaign is finally here, and it's definitely got us in the party spirit.

There's no cute animals or teary relatives in this advert, just dancing, music and merriment. Oh, and a bit of festive smooching.

Gaga and Bennett have collaborated together since 2011, and the track they have lent to H&M for this advert – It Don't Mean A Thing (If It Ain't Got That Swing) – is taken from their new album, Cheek To Cheek.

Obviously, we love the music, but this being an H&M campaign, the focus is really on the clothes. Naturally all the sartorial classics for party season are present: think fluffy feathers, mini dresses and a whole lot of sparkle. Extra points if you can spot the cameo from supermodel Joan Smalls, too.

Speaking about the making of the campaign, director Johan Renck, said:  'We were inspired by the glitz, glamour, and opulence of the 1940's Big Band era. The mood is one of festive celebration shot through with a strong sense of fashion and an underlying humour. It is intriguing, curious, exuberant, audacious, and filled with wonder.'

There's definitely one thing we're still very much intrigued by: Gaga's wig. Seriously, it's like a whole other person. Eat your heart (hair) out Cher…
