Billy WAS with Freefalls Entertainment but I think Michele said something about him not being there anymore or something like that to this effect? I can't remember.
According to the liner notes of the "America's sweethearts" soundtrack album, Bekka "appears courtesy of "12th Street Records"" so I'd assume she is signed with them but I don't have any further info on them than that.
I assume Rick is still with the German firm Hypertension whose address is (according to the "Crazy cool" CD):
Hypertension Music
St. Benedictstr 5
20149 Hamburg
Germany
Phone: 040 47 69 93 (I think!) Hope that helps!
