Asked about the criticism, the Absolutely Fabulous star replied: "So the critics - five middle-aged men - didn't like it. If you send your dad to see Viva Forever! on his own, then of course he's going to hate it. It was no surprise."
Producer Judy Craymer also defended the musical, asserting that it has had an enthusiastic response from audiences, and set out her long-term vision for the project.

"We just want to make sure we have the product right in London first. The critics were always going to give us a hard time, but the truth is it's sold out until June. Feedback from audiences has been amazing. Spice Girls fans are loving every minute."
She added: "Yes, it's been hard - but just like any show is hard to start from scratch and launch on the West End."
