We learnt recently that Steven Seagal has not only been teaching MMA to Anderson Silva (see Steven Seagal) but now also Lyoto Machida. Both fighters have been filmed training with Steven Seagal and crediting him with winning. Here is some film of the training and a following interview with Seagal and discussion from the aikiweb
You can see the interview with Seagal here
