Bebo turns 40! Preparations for Kareena Kapoor Khan's birthday bash begins. IN PICS

Bollywood's Bebo aka Kareena Kapoor is turning 40 and we can't keep calm. Just a day before the big day, the mommy-to-be was spotted outside her house all decked up in an all-white attire.

Ahead of her 40th birthday, she posted a note of gratitude on Instagram. She wrote, "As I enter my 40th year... I want to sit back, reflect, love, laugh, forgive, forget and most importantly pray and thank the strongest force up there for giving me the strength and thank my experiences and decisions for making me the woman I am. Some right, some wrong, some great, some not so... but still, hey BIG 40 make it BIG."

On the work front, Kareena will be seen sharing screen space with Aamir Khan in 'Laal Singh Chaddha,' which is an adaptation of 'Forrest Gump.'

Look at those balloons and birthday cake. Looks like everyone is going to have some super fun tonight!

Kareena and Karisma's father Randhir Kapoor was also seen waving outside her house. He recently joined Instagram and revealed that it was purely the decision of his daughters.

Bebo's sister Lolo aka Karisma was also spotted outside her house all dressed up in a black dress.
