Erin Andrews -- Awkward 50 Cent Kiss Was My Fault!

Don't blame 50 Cent for the awkward encounter he had with Erin Andrews at the Daytona 500 last week -- the hottest woman in sideline reporting says the blame lies squarely with her.

During the big race last Sunday, Erin was searching for Danica Patrick (to no avail) when she ran into Fiddy and ... well, it was weird.

But yesterday at LAX, Erin told our photog she was so frazzled in the moment ... the entire encounter was totally her fault and she's actually good friends (and even business partners) with 50.

The old "it's not you, it's me" -- we've heard that one before.
