Bruno Mars can't stop thinking about his new video.

The 27-year-old singer - who has proclaimed his forthcoming new album 'Unorthodox Jukebox' as ''darker and more aggressive'' than 2010 debut 'Doo-Wops & Hooligans' - thinks fans will love the accompanying clip to his new single 'Young Girls' because it is so different to anything he has previously done.

He told MTV News: ''Every day I'm thinking about the video. It's going to be something I've never done before, I promise you that.''

Bruno also explained the artwork for his new album depicts a gorilla in honour of one of the songs on the record and says the animal became the ''mascot'' for his latest work.

He added: ''On the album 'Unorthodox Jukebox' there's a gorilla on the album cover because I wrote a song called 'Gorilla'.

''And that was the first song we wrote for this album and it really set the tone for the entire project and it kind of became the mascot. Why not put it on the cover?''
