Colin Firth down with flu

The 'King's Speech' star was forced to miss out on supporting his wife at a lunch to promote sustainable fashion after he fell ill, reported Daily Express.

When asked where the 52-year-old actor was, his wife Livia Giuggioli said, "My husband is stuck in London with the flu. He couldn't get on the plane."

Tommy Hilfiger, Martha Stewart and designer Tory Burch were also at the lunch, which was held to support a campaign to create jobs and boost communities across the world through sustainable fashion businesses.
