"She calls me man of the house in her column but she is my superwoman," Akshay tweeted Friday alongside a photograph featuring Twinkle on the cover of a leading fashion magazine.
The couple got married in 2001, and they have two children together - son Aarav and daughter Nitara.
Twinkle, daughter of Dimple Kapadia and late Rajesh Khanna, was an actress and now she's a popular interior designer.
