The power couple shot for an ad campaign for jewellery brand Tanishq in Mumbai Tuesday.

"Back from Tanishq shoot with Jaya... loved it... relaxed, well controlled atmosphere ... wife seemed happy and comfortable! Must get her in front of the cameras with me... she is such a natural! More films perhaps with her in roles commensurate with our age (sic)," Amitabh posted on his Twitter page.

Amitabh and Jaya, 62, were last seen playing husband and wife in Karan Johar's superhit family saga "Kabhi Khushi Kabhie Gham" in 2001.

The 68-year-old also shared his experience of the shoot on his blog www.bigb.bigadda.com.

"Was a joy today to be in the company of Jaya on set, as we worked together after a gap of almost 10 years. The same studio, Filmistan, the same floor #3 and the same DOP - the director of photography, Kiran Deohans - as was for our film 'Kabhi Khushi Kabhie Gham'. Just sheer coincidence! And selling... what women like best, diamonds," he posted.
