Ummm what?

A source told Perezhilton.com that Taylor Swift was caught making out with boyfriend Conor Kennedy's cousin Patrick Schwarzenegger at a family event recently.

Uhhh oh!

The source doesn't sugarcoat it either; they say the family is NOT happy!!

Explaining the whole situation, the source reveals:

"Taylor and Patrick weren't kissing out in the open, but she wasn't being as subtle as she thought she was. The previous day, she was all over Conor, so she hooked up with two cousins on consecutive nights!"

"Conor doesn't know, but everyone else in the family does. They think she's a hanger-on and find her obsession with the Kennedy cousins disconcerting. Taylor lost the respect of everyone in the family. They despise her and don't want her anywhere near Conor or Patrick."
