I would have to say Michael Tao. They're in DIF I-III, Shine on You, and Love Bond together.

It's hard to say, depending on who you're thinking of, it could be Michael as mentioned in the previous post, but she has also worked with Bobby many times too such as Crimes of Passion, Take My Word for It, Shine on You, and they have a new unreleased series See Goon Kay On.
