Justin Bieber to collaborate with Ke$ha for new album 'Believe'

Justin Bieber will allegedly collaborate with Ke$ha on his new album.

The singer is currently working on his third studio LP Believe, which is expected to be released later this year.

Ke$ha will write for the set as well as "be a part of the song in a duet capacity", a source told Hollywood Life.

The 'Tik Tok' star - real name Kesha Sebert - has previously co-written tracks for Britney Spears, Miley Cyrus, Alice Cooper and Flo Rida.

Meanwhile, Bieber revealed last week that he is recording music with Lil Wayne for his new album.
