Box-office success, a string of endorsements and a blue-blooded prince as her beau, life is beautiful for Kareena Kapoor as the Bollywood diva turns 31 on September 21, 2011. So, birthday girl Bebo has all the reasons to celebrate. After the blockbuster success of Bodyguard, the girl is already looking forward to SRK's sci-fi extravaganza Ra.One, where she plays the female lead. Moving away from her flourishing career, talk about Bebo's personal front and there too, things are looking up for the Virgo girl. Because, the Chhote Nawab has already hinted about marriage being on the cards in 2012. And even though this might be Bebo's last birthday as a single woman, she has decided to keep it a low-key affair. Bebo and Saif Ali Khan are currently in the national capital to be at the side of the ailing senior Pataudi. Kareena, who loves spending time with Saif's family, has, therefore, cancelled all celebrations to be with them in Delhi. For love, it seems, Bebo will go extra miles, literally.
