Lindsay Lohan is back to her charming ways, “flipping big time” over a burrito.

The actress showed the crew of a credit card commercial shoot in Los Angeles exactly why she’s been reduced to er, shooting credit card commercials when she discovered some extraneous onions in her lunchtime snack.

She ranted at her little on-set helper, “I didn't f***ing order this!"

A source adds, "Everyone was just looking at each other with open mouths.

"It was a minor thing but she caused such a scene - no one could believe it," according to the Mirror.
