Their first endorsement as a couple saw them in a mobile service brand ad Saif Ali Khan and Kareena Kapoor have signed up to do an ad for a footwear company for a whopper.

Says a source close to the couple, "Saif said yes first. He looks after and is involved with the creatives of all the ads he does. He loved the concept.

The ad will be displayed on 100 hoardings across India and near major roads across Mumbai. Apart from the exposure, the jodi has been paid a huge amount of money to endorse the footwear for men and women." This will be Bebo's fourteenth ad and the chote nawaab's ninth. Kareena is the only actress today who has so many ads.

"Though the two have always been very choosy about endorsing products, shows and films together the concept of the ad (kept under wraps) was funny, whimsical and romantic.

As of now, the only film the couple are doing together now is Saif's home production Agent Vinod."

Yesterday, they shot for the print ad campaign photographed by Prasad Naik.

The couple is being styled by Anahita Shroff Adjania (Love Aaj Kal). Last week Kareena also shot for her bike ad the bike which is also endorsed by Aamir Khan.
