Actor Terrence Howard (pictured) and his ex-wife, Michelle Ghent (pictured), are obviously a match made in hell, so why did they reportedly arrange to vacation together in Costa Rica last week with his family members? And why are they now duking it out verbally, with Ghent accusing Howard of giving her a beat down after a heated argument ensued. Howard, on the other hand, is claiming that Ghent maced not only him but his family members as well, reports TMZ.
