When is a Bubble a Booblé and a Soufflé a Sufle?

Mrs Bucket - or Old Ma Hurlé?

If crooner Michael Buble is pronounced as Booblé, does that mean:

1. I can try and bake a sufle for Christmas dinner dessert?
2. I have been hanging baublés on the Christmas tree?
3. We will have a glass of booble on Christmas morning?

Or is Michael Buble just pulling a Hyacinth Bucket from the comedy Keeping Up Appearances who insisted on being called Mrs Bouquet?

Whatever next?
