A Robert Pattinson fan has posted a hysterical, and slightly confused, rant on the internet, over the news Robert's girlfriend has admitted an affair with a married man.

Kristen Stewart owned up to her relationship with director Rupert Sanders after intimate photos of the pair emerged in a US magazine.

The pair met whilst shooting Snow White And The Huntsman, and both have released statements apologising.

It was not enough for the fan who calls herself nuttymadam3575.

She posted a video on YouTube in which she calls for K-Stew and R-Patz to be "left alone" to sort out their problems in private.

The girl breaks down in tears several times, and at one point, contradicting her earlier request for people to "leave them alone", nuttymadam3575 calls Kristen "stupid" for getting caught.
