According to Bollywood Mantra, the couple plan to get engaged in February 2012 and will tie the knot in October.
"Bebo and Saif are getting married by the end of 2012," a source close to the actress said. "The engagement date has also been chalked out around Valentine's Day. Bebo is looking forward to the engagement."
Kapoor, who has worked with Shah Rukh Khan, Salman Khan and Aamir Khan, is reportedly keen to have all of them at her wedding. She has already informed her friends to keep themselves free during this period and wants every one of them to be part of her wedding.
"The engagement is also going to be a big celebration," the source continued. "The family members are already talking to their friends to block their dates for the occasion. She wants all her friends to be there at the wedding.
"Kareena is rushing against time to complete all her film commitments. By the middle of next year, they will both be comfortable in their work space as Saif's own production (also starring Kareena) Agent Vinod will also get released by that time.
"Saif and Bebo will take 15 days off both for marriage, and about ten days for the engagement."
For the honeymoon, the pair will apparently travel to one of the 3 Idiots star's favourite holiday destinations - Switzerland or Italy.
Kapoor has reportedly chosen Ritu Kumar to design her wedding dress.
