Kim Kardashian is many things: A reality TV star, a mother-to-be, a businesswoman and entrepreneur. But the world’s most famous porn star? Not so much.

Yet one of TV’s most (hmm, how do we say this — controversial? headline-craving?) outspoken reality stars of yesteryear is claiming just that.

Spencer Pratt, who enjoyed reality TV fame on MTV’s The Hills circa 2006-2010 along with wife Heidi Montag Pratt, is making his way into the headlines once again. And this time, it’s because he’s made some very interesting statements about Kim K.

When asked if he feels threatened by other reality stars, blond-bearded Hills vet told Yahoo OMG, “It's like any Royal family, she is just from a different Royal land. Kim Kardashian is from Mars and we're from Earth, you know what I mean?

Spencer didn’t stop there. "But I CAN tell you that Kim Kardashian is the world's most famous porn star! She would not be anywhere, I guarantee it, without that sex tape."

Look, we get it: Kim has a sex tape. It was distributed by her then-boyfriend Ray J back in 2007 — and it does seem to have made Ray J think that he’s the reason Kim became famous.

Calling Kim a porn star, just because of some video she made when she was young... and that she never meant to be released? Come on, Spencer. That’s low. Even for you.
