Demi Lovato is teaming up with Missy Elliott for an unlikely collaboration.
 
The singer/actress is currently recording her third album after a stint in a treatment center last year to deal with a number of personal issues, including self-harming.
 
Now Lovato has revealed she's enlisting the help of rapper Elliott for a collaboration.
 
She's taken to Twitter to post a photo of herself recording with the hip-hop star, writing, "4 am: Missy Elliott and demi lovato...working hard in the studio!"
