If Kristen Stewart really wants to win Robert Pattinson back, we don’t think avoiding soap and hot water is the way to go.

An “insider” with the “Twilight” star revealed to RadarOnline.com that K.Stew has been “inconsolable” since news of her affair with movie director Rupert Sanders. So much so that she’s refused to shower and wash her hair.

Oh, yeah. Nothing like a heavy load of body odor to make the man you love come running back.

“She is beyond mortified and humiliated and she is also broken hearted,” the source says. “She says she truly loved Rob. She says he was her soul mate, but she blew it and now she is scared that she has lost him forever.

Kristen hasn’t showered or changed or washed her hair in several days,” the insider reveals. “She is laying around in her T-shirt and shorts and eating ice cream. She really wants to believe that she can win back Rob, but I think deep down she knows that isn’t the case.”

Yeah, Kristen might wanna look into dating Oscar the Grouch. He sounds like he’d be more her type.
