The 35-year-old singer shared a photo of himself and his longtime collaborator hard at work in the recording space on Tuesday (29.03.16), but kept fans guessing about their music-making session.

Alongside the picture posted on Justin's Instagram account, he simply wrote: "Currently."

The pair have long been rumoured to be working on a country music album together after Timbaland teased the idea last year, saying he's keen to make such a record.

Speaking about Justin, he previously said: "He's from Tennessee, I'm from Virginia. It's only right that we try and tap into what we was raised in ... 'Drink You Away' was on 'The 20/20 Experience'. It's now starting to be one of the biggest songs. We always wanted to do country music - we thought some of them lyrics are country."

While it's not known if Justin is working on a follow-up album to 2013's 'The 20/20 Experience', he has also been in the studio recently with Pharrell Williams and country band Little Big Town.

However, he is keeping everything tight-lipped, as, like the TImbaland situation, he also wrote "currently" alongside a picture of the 'Happy' hitmaker.

But Justin did reveal he was writing with Little Big Town.

Taking to his Instagram last week, he shared a picture with the caption: "with NBD... Just writing with @littlebigtown This band is the truth!! So good!!!! (sic)"
