JJ Music Monday: Mateo!

Mateo‘s new track, “Say It’s So,” is this week’s pick for JustJared.com and 102.7 KIIS FM‘s JJ Music Monday!

The 24-year-old up-and-coming singer teamed up with Alicia Keys for the hot new R&B song.

After a brief stint on MySpace Records, Mateo began working with Krucial Keys, who co-wrote and co-produced many of Alicia‘s biggest records like “No One” and “Like You’ll Never See Me Again.” Look out for more from Mateo in the coming year!
