Vikings' Rollo Lothbrok will look markedly different as season 4 begins.

Actor Clive Standen attended the Monte-Carlo Television Festival earlier this week, eschewing Rollo's former chest-length locks in favor of a close-cropped look.

"The reason I haven't got long hair now is a big, big plot spoiler for season 4," Standen told French news outlet TFI. "We're in the middle of season 4 filming, we're on episode 5 and we're doing 20 episodes this year. So we're in it for the long haul for season 4."

It's safe to say that Rollo's new 'do is closely tied to his impending nuptials. Although the Viking is clearly working to emulate the Parisian style, it sounds like it will take a lot more than a haircut to placate his bride-to-be.

"That's going to be part of the uphill struggle that Rollo has essentially because the French Princess Gisla (Morgane Polanski) is not actually a big fan of the Vikings, let alone Rollo. So he has a mountain to climb and he's going to have to win her to his side," Standen teased, adding that "there's going to be some fireworks ahead" for the disparate characters.
