Russell Armstrong, the estranged husband of "The Real Housewives of Beverly Hills" star Taylor Armstrong, was found dead of an apparent suicide Monday night.

The 47-year-old businessman reportedly hanged himself in a Mulholland Drive home and left no note behind. He was found by a roommate.

Russell's lawyer Ronald Richards told TMZ that his client had serious financial problems and was distraught over the breakup of his marriage. Apparently, Russell had been staying with a friend who lived in the home where his body was found.

"I feel bad because his credit cards weren't working,"  said Richards. "He had tremendous financial problems.

"He was also extremely bummed out about the divorce with Taylor," Richards added. "As far as a will, even if he does have a will, they don't have any assets, so I'm not sure what there would be left to leave."

Taylor Armstrong filed for divorce in July after about six years of marriage-- accusing Russell Armstrong of "ongoing physical and verbal abuse" -- the Huffington Post reported.

RadarOnline.com reported that "a source close to the situation" described Taylor Armstrong as being overwhelmed with grief.

She "has been up all night," the source said. "She is hysterical, and can barely speak. She has no idea why Russell would do this. She doesn't know how she is going to be able to tell her daughter, Kennedy."

So far, at least one fellow "Real Housewives" star has taken to Twitter to express his condolences.

Shane Keough, the son of former "Real Housewives of Orange County" regular Jeana Keough, tweeted:  "Everyone please keep Housewife Taylor Armstrong and her family in your prayers as they deal with the horrible loss of Russell Armstrong."

While the allegations of physical abuse took some of the reality show's viewers by surprise, Russell and Taylor's separation wasn't entirely unexpected. Toward the end of the show's season, Taylor Armstrong became outspoken about her marital dissatisfactions, and questioned whether she should remain with her husband.

In one episode, Taylor Armstrong threw a lavish birthday party for the couple's young daughter -- seemingly with little support from her husband -- and was shocked when he presented their daughter with the gift of a new puppy in front of their guests. The couple had previously agreed not to give their daugher a pet for her birthday.

Tension between the two was apparent in other instances, when Russell Armstrong wasn't enjoying himself at a particular party or event and Taylor was trying to have a good time. In these cases, Russell was portrayed as controlling and somewhat ill-humored.

While the Armstrongs appeared to be quite wealthy on the show, later reports surfaced that Russell Armstrong was having financial difficulties the same year he married Taylor. TMZ reported that the businessman filed for bankruptcy in 2005 after losing much of the money he made in the dot.com boom. According to the documents, Armstrong claimed to have under $50,000 in assets.
