Rumours gone Haywire - Rihanna is still riding with Chris Brown

 

Rihanna has once again taken back Chris Brown ... at least for now ... 'cause the two were rollin' around L.A. together in the same expensive car yesterday.

As I previously reported, the two have been breaking up and getting back together more often than Van Halen ... but yesterday, it seems they were "back on" for the day.

In fact, Rihanna even posted a pic of herself and Breezy taking a ride on instagram.

Think they'll make it through the week?
