Back On? Mariah Carey Posts Flashback Snap With Ex

Mariah Carey is a woman of a few surprises. The 47-year-old on Friday posted a shot to Instagram in which she's posed with her ex-boyfriend Bryan Tanaka, 33, as the two sipped out of the same chocolate shake.

She captioned the image #fbf, meaning Flashback Friday, and it was not immediately clear if the singer was in a nostalgic mood or if there could be a rekindling of the five-month romance, which ended about five weeks ago.

At the time, reports of the breakup pointed to a number of issues, including Tanaka's spendthrift habits, in addition to his burning jealousy over her cordial relationship with ex-husband Nick Cannon, the father of her six-year-old twins Monroe and Moroccan.
