/>This Valentine's Day seems to have brought on a prolonged season of love in Bollywood.

And what better way to celebrate love than to mix business with pleasure? Abhishek Bachchan's new IDEA ad is a very special gift to his wife.

On her birthday in November, Aishwarya Rai Bachchan flew down to Agra to join her husband who was shooting an ad there.

The IDEA ad, shot by Amit Sharma has distinct elements of Abhishek's character in Shaad Ali's Bunty Aur Babli. It also seems to echo Govinda's Taj Mahalian encounter with Shanon Esra in Salaam-e-Ishq.

Says a source, "Abhishek and the Taj Mahal seem to be inextricably bonded. He shot Tera Jadoo Chal Gaya and Bunty Aur Babli at the Taj, and now this ad. Which was really special because it was on Aishwarya's birthday.

And the Bachchans were all there in Agra. And why just Abhishek? Even Aishwarya has shot so many films at the Taj Mahal including Shankar's Jeans."

The idea was to capture Abhishek as this small-town dude, a sassy tourist guide who meets this very unusual blonde tourist at the Taj Mahal.

Says the source, "Abhishek had great fun shooting the ad. He'd do his shot and rush to be with his family. It was a very special birthday for Aishwarya."
