I answered my own question with google and found a guardian article from 2008 that explains it was Sullivan...
"Speaking of David's birds, it is the manner in which he dealt with the suicide of a former girlfriend, the porn star Mary Millington, that suggests he may yet summon the powers of recovery to see himself through this latest distress. After Millington took her own life, he declined to attend her funeral but was able to rally sufficiently to swiftly turn out a film project cashing in on the interest her tragic end had brought. It is clearly what she would have wanted, and despite Mary Millington's True Blue Confessions being condemned by swathes of Millington's fans as ghoulish sexploitation, it was successful enough for Sullivan to hold back the tears again and release another the next year."
