Christina Milian -- Grounds For a Twerkout (VIDEO)

Christina Milian has a great way to bounce back after a breakup -- hit the floor for a playful workout with your twerk guru. Works for us.

Milian and trainer Lexy Panterra decided to work their glutes ... although we suspect this session is more about Christina sending messages, such as: 1. Hey guys, I'm single, and 2. Hey, Lil Wayne ... hungry for cake?

Either way, this looks like a great way to shake off any lingering heartbreak ... while staying in shape, of course.
