Following his latest bust-up with on-again, off-again galpal Kate Major, d-bag dad Michael Lohan was sent to rehab for his problems. Until now, it was a mystery as to what the 51-year-old was abusing -- besides his girlfriend. However, a source has revealed to Radaronline.com that Lindsay's troubled pop is receiving treatment for abusing steroids and contending with co-dependency issues. Right now, he's doing a stint in Palm Partners in South Florida while residing at a halfway house across from the facility. Supposedly, Lohan is such an expert at addiction that he will soon be overseeing interventions when he completes his program next month. One source tells Radaronline.com, "When Michael is released on March 16, he will be doing interventions himself." The fame-whoring freak is also in talks to host a radio show with DJ Jeremy Loper. The insider adds, "The show will address all kinds of issues from sex, addictions, clearing up gossip and various real life situations. Sounds like a new Love Line." Lohan is no stranger to the airways -- he was host of Reality Talk Radio on Clear Channel's WIOD last year. At the end of the day, when Lohan talks, we're willing to bet people won't listen.
