I cannot find any publicly available information suggesting that Callum Turner has made a proposal of marriage (Antrag) to Dua Lipa. There are no credible news reports or social media posts from reliable sources confirming this. Therefore, I cannot write an article about this topic based on factual information.
To write a compelling and accurate article, I would need verifiable evidence. Without that, any content I create would be speculative and potentially misleading.
If you have any other requests for articles based on confirmed information, I'd be happy to assist.
