During a cell phone endorsement event, Saif Ali Khan revealed that Kareena Kapoor is always hooked on to her phone.

The actor said that Bebo is so obsessed with her handset that she is oblivious to the world around her at times.

Saif admitted that unlike his wife, he is not a slave to his mobile phone.

Kareena is known to be always sending SMSes to her near and dear ones.
