Inside Jahaan's Birthday, Courtesy Shanaya Kapoor: "No One Messes With My Little Brother Except..."

On Jahaan's birthday, Shanaya Kapoor's post takes the cake

Happy birthday, Jahaan Kapoor. Maheep and Sanjay Kapoor's son Jahaan celebrates his 16th birthday today. Birthday festivities of the 16-year-old Kapoor began early at midnight, glimpses of which have been shared on Instagram. While Maheep and Sanjay Kapoor shared heartwarming messages for Jahaan, his sister Shanaya Kapoor posted a cheeky birthday wish for her "little brother." Tough sister Shanaya wrote about her one rule when it comes to Jahaan: "No one messes with my little brother, except me!Happy birthday my fav. PS - Swipe to see Jahaan getting fed up with me," she wrote. Shanaya indeed packed a bunch of goofy photos of Jahaan from last night's birthday celebrations. While the birthday boy was busy face-palming, Shanaya looked adorable in tie and dye co-ords.
