Eminem is taking over Twitter today, July 24th, for a Q&A session with his fans. But he isn't just answering any random questions. Beginning at 1:00 p.m EST, Mr. Mathers is only answering a select 12 questions about the film Southpaw, which he executive-produced the soundtrack for. Fans should ask away using the hashtag #DearSlim. Southpaw, which stars 50 Cent and Jake Gyllenhaal, hits theaters today as well.
