Listen to Jennifer Lopez on iHeartRadio

Jennifer Lopez is revealing more details about her forthcoming eighth studio album.  "Billboard" says the star previewed six of its tracks during an intimate gathering in Malibu on Friday. 

Among them is a Max Martin-produced song called "First Love," which is set to serve as her next single when it arrives in May.  Jennifer says she had "always" wanted to work with hit-maker Martin and "sought him out" for song. 

The singer also revealed that at least two of the songs on the album were written by Chris Brown.  He penned a ballad called "Emotions," as well as a dance track called "Big Booty," which will feature J. Lo's frequent collaborator Pitbull.  

Jennifer says she went into recording her new album after she "realized [she] was stronger that [she] thought," entering the studio on the heels of her divorce from Marc Anthony and touring around the world with her young twins.
