Abhishek Bachchan shot for a new commercial for beauty brand Lux despite an injured back.

"Sometime ago, Abhishek was shooting for 'Dum Maro Dum' and while on the sets he hurt his back badly and was down with a sprain. But that didn't dampen his spirits or affect his shooting schedule with Lux, " said a source.

"Since Aishwarya and he had already allotted time and the production team was ready to shoot for the Lux Superstar offer commercial, Abhishek didn't bat an eyelid and continued to move on with the shoot and remained high spirited, " the source added.

The commercial has Abhishek and Aishwarya in glamorous avatars.

The Lux Supertstar offer announces an opportunity for consumers to meet the celebrity couple in London by purchasing Lux products.
