What will Robert Pattinson's legion of female fans make of this?
The vampire heart-throb has given his mane of 'run-your-fingers-through-it' hair the chop.
During a question and answer session Rob and Kristen gave a rare insight into their relationship.
Asked if they had any nerdy habits, the British actor volunteered the information that Kristen "only watches the cooking channel".
He added: "Especially on-set - she has a TV in the makeup trailer.
"It's her only diva-ish behaviour - having the cooking channel on all the time in every room."
Kristen's comeback was: "You reap all the benefits!"
From the couple's exhange it would perhaps be safe to assume Kristen is the one who's in charge in the kitchen.
