Sanjay Dutt penned a heartfelt note for Mahesh Bhatt on latter's 71st birthday, expressing his gratitude to the veteran filmmaker for standing by him at a time when he needed a friend.

"I read somewhere that a friend is someone who understands your past, believes in your future and accepts you just the way you are. Luckily, I got to experience this kind of friendship with you. When the entire world turned their blind eye to me, you were standing tall right beside me. On your 71st birthday, accept this letter as a token of gratitude for everything you have done for my family and me," Dutt wrote on Twitter.

Happy Birthday Bhatt sahab
