Brunette Lucy Mecklenburgh, 21, wanted to see if blondes have more fun, but when she showed her new lighter roots to fiance Mario Falcone on Sunday's episode of The Only Way Is Essex, she was less than happy with his response.
He first exclaimed: 'Oh my god,' - with Lucky commenting: 'You're gritting your teeth.'
She explained that she expected a better response than that, and eventually he began laying on the charm.
He said: 'Making love to you like that, it's going to be like like cheating.'

Meanwhile, Gemma continued to moan about her ex - James Argent.

Several hours later, the pair clashed off screen - with Argent claiming Tom ripped his top.
Lydia meanwhile was quick to rant about James, saying: 'He's 18 stone, lives with his parents, he doesn't have a car...he's embarrassing. When we get married, and the room is asked if anyone objects to the marriage, fat Arg is going to run up the aisle and say no.'
