Just when you thought ”Twilight” fans had a healthy grip on reality — TMZ has learned, lady Twihards are invading bridal boutiques, secretly lying about being engaged … so they can try on a replica of Bella’s wedding dress from the new flick.

The $799 replica is being sold in Alfred Angelo bridal boutiques everywhere — and people who work at the chain tell us the scheming fans are driving them crazy, making it extremely difficult to conduct business.

By the way, we really don’t think Twilight fans have a healthy grip on reality.
