A rep for Jesse James has dismissed reports the disgraced TV mechanic filmed more than a dozen homemade sex tapes, including a clip with his estranged wife Sandra Bullock.

The "Blind Side" star walked out on James and left the couple's marital home in March when allegations of his infidelities first surfaced.

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.

A rep for James tells, "The claims of sex tapes are untrue and completely fabricated."

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.
