Looks like Kareena Kapoor is signing up to play the role of a lifetime - a blushing bride in real life. The grapevine says Bebo will tie the knot with her long time beau Saif Ali Khan in February 2012.

Apparently, the Kapoor lass has been making frequent trips to New Delhi for her bridal dress, which will be designed by Ritu Kumar, a favourite of mom-in-law Sharmila Tagore.

Saif's mom wants his new bride to look every inch a royal and who better than Ritu Kumar to add the regal touch. Kareena, who recently signed Madhur Bhandarkar's Heroine for a reported 10 crore, is going slow on signing new assignments. The grapevine also has it that the couple is likely to make a formal announcement about their wedding sometime in December, when Saif's home production Agent Vinod releases.
