Terrence Howard has reportedly acted impulsively again by marrying a woman he has been dating for a month. Representative of the "Iron Man" star has not responded to the rumor, but should it be true, then this would be the actor's fourth marriage.

Howard had been seeing a Canadian woman named Miranda and bragging about her to his friends and family, including his ex-wife Michelle Ghent. "Terrence called up Michelle to tell her about the marriage and taunt her about it," a source close to the situation revealed to RadarOnline.com. "She needs to cut him off for good."

Radar also reported that he even took Miranda to red carpet events including "The Best Man Holiday" premiere in Los Angeles on November 5. They were wearing wedding rings at that time. "It's another one of his outlandish moves ...he only knew and/or dated her for about a month!" sources said.

Howard may be enjoying a honeymoon but Ghent is still fighting him in court. The third wife has accused the "Prisoners" star of failing to pay court-ordered spousal support. She also said he left her with credit card bill for the reconciliation attempt in Costa Rica earlier this year.

"Since the commencement date of 5/15/12, Terrence Howard has only made sporadic payments to me totaling $18,435 and owes an average sum of $63,303 ...the Court finds that Terrence Howard owes me $122,221.64 including interest ... legal fees to my lawyer, $15,500," the docs obtained by Radar read.

Ghent continued her allegation, "During our recent reconciliation, Terrence Howard frequently made charges on my credit cards as Respondent does not have his own credit cards and promised to reimburse me for his charges. At Terrence Howard's request, I charged our 7/2012 trip to Costa Rica on my credit card. The unreimbursed charges for the Costa Rica trip and prior charges are approx. $18,282."

Ghent earned a restraining order against Howard after she accused him of punching and kicking her during the Costa Rica vacation.
