Ahead of her 40th birthday, Kareena Kapoor Khan had posted a note of gratitude on social media. "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, [sic]" Kareena wrote on Instagram.
