Who? American singer, actress, film director
Real? No. The stag loop circulated, but it was almost certainly not Barbra Streisand.
Back in the 16-millimeter stag loop days, before hardcore porn was openly shown in movie theaters, one short sex film supposedly showed a pre-stardom Barbra Streisand fucking on camera. This was probably just a pervy underground urban legend, started to sell/rent extra copies of an otherwise unexceptional porn loop.
The Village Voice wrote, “The so-called Streisand film merely shows a young woman with a large nose having sex on camera; though available copies have become murky through generations of cheap dubbing, any resemblance seems far-fetched.”
Al Goldstein played the alleged Barbara Streisand sex film on his cable show in the 1980s, introduced by a staffer’s “it’s probably not her, but we’ll let you the viewer decide for yourself” disclaimer. The segment is available on the DVD compilation Midnight Blue: Vol. 3: Celebrities Edition.
Barbra Streisand herself discussed her alleged porno past in her 1977 Playboy interview:
I couldn’t resist the temptation to see what the actress looked like — and also to check out her performance — so we got a copy. The film, naturally, is very blurred. The girl has long hair, like I did back in the Sixties, although she was chubby, while I was very skinny. But the dead giveaway came when the camera zoomed in on her hands around the guy’s you-know-what. There they were: short, stubby fingers! Definitely not mine. So all you would-be buyers, don’t waste your money.
Some sources identify the lookalike as pornstar Tasha Voux. This is definitely not true either. Tasha Voux began her porn career in 1984 at age 26. The fake Streisand stag film dates back to the 1960s or early 1970s.
There’s a good discussion of the fake Barbra Streisand sex tape on the Snopes forum.
Barring some exceptional new evidence, it’s safe to say that the Barbra Streisand sex tape was a lookalike fake.
