After three collaboration songs, Rihanna and Chris Brown have another collaboration song titled "Put It Up," which recently went viral. However, the song was released by neither of them. It was leaked on April 19, Sunday.

"Put It Up" was said to be recorded after the release of Rihanna and Brown's third first collaboration song "Nobody's Business," which is from Rihanna's 2012 album titled "Unapologetic,"

The publication said "Put It Up" was intended to be featured on Brown's album originally titled "Carpe Diem" but was renamed "X" after some legal troubles. However, when the "X" album was released in September 2014, "Put It Up" was not included.

Rihanna reportedly prohibited Brown from using "Put It Up." Had it been included in Brown's "X" album, it would have been their fourth collaboration song with the remix songs "Birthday Cake" and "Turn Up The Music" being the first and second ones.

In "Put It Up," Rihanna sings, "I'm gonna explore all of your body," to which Brown responds, "Treat me like I'm your property / I'm about to be your biggest fan." An audio of the song is available on Direct Lyrics.

Neither Rihanna nor Brown has commented on the leaked collaboration song.

Meanwhile, Rihanna is currently in Hawaii to attend the wedding of her longtime assistant Jennifer Rosales to Aaron Davis, Daily Mail reported.

While in Hawaii, Rihanna shared some sexy of her photos to her 17.3 million Instagram followers.

In one photo captioned "Ginger," Rihanna flaunts her booty while in a bikini. In another photo captioned "girlz on film," she is seen sitting seen sitting on a sun lounger holding up her phone in one hand like she is trying to take a photo.
