The Black Eyed Peas rapper has apparently been approached to produce a number of tracks for the teen singer's second studio album, with talks of a possible collaboration also taking place.
"There has been talk for him to do some things with Justin, now that the Black Eyed Peas are taking a brief hiatus," a source told Hollywood Life.
"Will has plenty of time to help out on working with Justin. They have certainly had discussions."
The source added: "But what I have also heard is Justin is taking his time with his next album, going through plenty of producers and collaborators to make sure everything is just right."
The follow-up to Bieber's chart-topping debut album My World is expected to be unveiled next year.
The 17-year-old currently features on Chris Brown's new single 'Next To You', which is released on August 14.
