"And now we come to today and I can finally say I passed with flying colours. U are what we all say women should be so fly high my darling and don't tone down ur shine for anyone. I've got ur back! happy adulthood. You have the tools so use your powers for good," she added. Ajay Devgn wrote an Instagram: "Happy Birthday, dearest Nysa. Small joys lik e this are the only 'break' in stressful times like these. Also, a sincere prayer for all those who need healing." Meanwhile, on the occasion of daughter Nysa's birthday on Tuesday, Ajay Devgn announced his digital debut with a web series titled 'Rudra: The Edge Of Darkness'. /IANS
