On Tuesday, Bullock's aides spoke out against claims that James possesses a graphic sex tape featuring the actress, which he could possibly use as leverage in a divorce case.
Now James' rep has cleared up Internet reports which suggest he's recorded several tapes with mistresses featuring Nazi-themed paraphernalia.

James, believed to be receiving treatment in an Arizona facility, was shamed last month by the online leak of a photo in which he poses as Nazi leader Adolf Hitler.
