Bollywood stars celebrated Raksha Bandhan, a predominantly Hindu festival that honours the bond between brothers and sisters, on Sunday. Celebrated by South Asian communities around the world, the day is traditionally marked by sisters tying a charm called a rakhi around the wrist of their brothers, symbolising care and protection. In turn, brothers are expected to offer their sisters gifts, thereby cementing their bond. Priyanka Chopra Jonas, who's currently in London, posted images of herself with brother Siddharth Chopra. "First time together in five years on Raksha Bandhan! Love you lil brother <a href="https://www.instagram.com/siddharthchopra89/">@siddharthchopra89</a>," she posted. Chopra Jonas also had a message for her fans, adding: "<a href="https://www.instagram.com/explore/tags/happyrakhi/">#HappyRakhi</a> to my army of brothers! Sending love and rakhis wherever you are…expecting my gifts soon too 😂- Love, Mimi." Suhana Khan, the daughter of Bollywood superstar Shah Rukh Khan and interior designer Gauri Khan, reshared a photo of herself with her brothers Aryan and AbRam in her Instagram Stories. She simply said: "Love you". While their path to Bollywood is not yet certain, both Suhana, 21, and Aryan, 23, have a huge following on social media. Bollywood actress Sara Ali Khan posted a video of herself playing knock knock jokes with her brother Ibrahim. "Happy Rakhi Iggy Potter," she posted, using the nickname she's often used for her brother on social media. The siblings are the children of Bollywood star Saif Ali Khan and his ex-wife, actress Amrita Singh. While Sara is already four films old, Ibrahim is rumoured to making his Bollywood debut soon. Actress and activist Dia Mirza meanwhile shared photos of her stepdaughter Samaira tying a rakhi on the wrist of her son, Avyaan who was born in May. "Our first Raksha Bandhan. We will love and protect each other," the former Miss Asia Pacific posted. Samaira is the daughter of Vaibhav Rekhi, who Mirza married in February. Avyaan is their first child. Bollywood star Akshay Kumar also marked the day by paying homage to his sister Alka, whom he called his "go-to person". "Someone who’s always stood by my side, corrected me when I’m wrong, happiest for my achievements. The most selfless person I know, my sister Alka. I wouldn’t have been the person I am without you.
