Chris Brown was recently spotted lurking in the comments section of Rihanna's Instagram.<br /><br />Brown commented three separate times on two photos Rihanna posted of herself to promote her lingerie line, Savage x Fenty. Each identical comment was wordless, as Brown simply used the blushing face emoji. <br /><br />Brown and Rihanna stepped out as a couple in 2008. In February 2009, Brown assaulted Rihanna during an argument that led to "visible injuries" and her hospitalization. <br />
