Dianne had brunette hair until 2016, when she dyed it very orange/red. Here’s a photo from May 2016. This is WELL before she did Strictly. She was still living in Aus at this point.
I don’t think we can blame strictly for Diannes love of red hair. I follow her & Joe a bit, I was a massive fan when they first got together but now I don’t really care 😂 but I still like them both. She’s really quirky. Their house is filled with mismatched, colourful crap she buys at charity shops! Her hair, clothes not decor are my thing but she owns it. & good for her.
That said, I wouldn’t be sad if she went more natural. I think she’d look lovely.
