Justin Bieber's manager has sparked rumours the singer is recording with Ed Sheeran.
The Baby hitmaker is currently at work on his acoustic album.
Bieber hit the music studio on Tuesday night and at the same time his manager, Scooter Braun, tweeted about being in the studio with Sheeran, MTV News reports.
"Hashtag just saying," Scooter caption a photo of the English singer-songwriter.
Sheeran later retweeted the message. Scooter later logged back on to tease fans about the recording session.
"Not gonna lie. There is magic in the studio tonight. Truly honored to be here," he wrote.
Sheeran has previously written hits for One Direction and Taylor Swift.
The singer on Wednesday said he didn't see collaboration with the boyband or the country music singer in the future.
And he seemed to put any ideas for a duet on ice, unless it "made sense".
"I find that collaborations sometimes are overly forced and they're not supposed to work. You should only collaborate if a collaboration makes sense," he told American radio host Ryan Seacrest.
Bieber's acoustic album is set for US release on January 29.
