This is getting ridiculous! Sometimes we think they're doing this just to screw with us...

Rihanna and Chris Brown went shopping at Wild Style by Joyrich in West Hollywood yesterday, and they made no attempt to fly under the radar. In fact, RiRi seems to be rubbing their reunion in everyone's face as she Instagrammed the above photo and wrote, "This sh*t look like a toupee," referencing lyrics from Brown's 2010 hit "Look At Me Now." (Rihanna also snapped another shot of herself and added, "Yellow model chick in my yellow ass dress with my yellow n***a X.")

Despite recent reports that Chris was getting cozy with not one but two unidentified blonde girls earlier this month, a source tells Us Weekly they're still together, but have been fighting a lot. "Every second it's a blow-up and then full on in love," the source says. "She's touring and working her [butt] off, and he's working his off in the studio."

A few weeks ago Chris told Ryan Seacrest how "remorseful and sorry" he was for treating Rihanna so badly, then a few days later he said they weren't together anymore, and just a few days after that he told Matt Lauer that everything was "fine" with the two. Maybe they'll make it to the end of the month without splitting again?
