Last week, Kyle Richards wrote in her Bravo blog she was “put off” by things about her sister Kim’s new boyfriend, Ken Blumenfield. At first, we took that with a grain of salt, but then she wrote on her website yesterday that she was leaving it to Kim to speak up about the truth. Well, the truth came out anyway. According to Radar Online, Kim’s new beau has a DUI arrest on his record.

Today, a less-than-flattering mugshot of Kim’s BF Ken Blumenfeld surfaced. Reports state Blumenfeld was arrested for a DUI in 2009. This raises some questions since Kim — who entered rehab shortly after Real Housewives of Beverly Hills Season 1 wrapped — has struggled with her own issues with alcohol.

As one source for Mail Online states, “Kim went through a lot last year with her drinking problem and the pressure from the show and her relationships only trigger Kim’s addiction.”

But it’s not just Ken’s spotty past (or the fact that he may still be active on Match.com) that are sending red flags. A source for Radar Online called the man “controlling” and another insider told the Mail Online that he’s “not right” for the 46-year-old reality star. Kyle also revealed on the show that Kim’s kids have called Ken controlling and aren’t fond of him.
