In AmE "gone" can be used instead of "been" in this case.
e.g. Have you ever been to France? (BrE)
e.g. Have you ever gone to France? (AmE)
AmE can be really confusing to people like me who grew up being taught BrE.
Is that so?! Quite confusing to me. I hadn't noticed it, but as bhaisahab pointed out, the correct form should be '...she's been there...', because gone suggests that she hasn't got back yet. Hope some Americans let us know if been is that common in AmE too.
