More tragedy for JENNIFER HUDSON as her brother is arrested for allegedly repeatedly stabbing a love rival in the face in front of his wife. 

Cops say Stephen Simpson went into a jealous rage at his estranged spouse's apartment in Michigan Monday night.

According to WWMT,  Simpson, 45, who is J-Hud’s half brother, has a long history of domestic violence. Police claim he knifed his victim several times, including in the face, before they fled to seek help.

Simpson was already on probation after being arrested multiple times in the past – the most recent for assaulting his wife on Super Bowl Sunday.

Officers are unsure whether Simpson's wife or her lover was the intended target.

South Haven Police Department Detective Detective Adam DeBoer said: “She locked herself in the bathroom until he left. It appears to be an ongoing feud over a woman.”

It is unclear whether Simpson, who shares a father with Jennifer, has a close relationship with the Oscar-winning singer, 32.

As The ENQUIRER previously reported in 2008 Jennifer’s  mother, brother and nephew were murdered by William Belfour, the estranged husband of her elder sister Julia. In July 2012, Balfour was sentenced to three life sentences without parole.

Simpson remains in custody in Michigan and is expected to be charged with home invasion and attempted murder.
