Bollywood actor Aamir Khan is celebrating his 53rd birthday and received an unexpected witty birthday wish from former India cricketer Sachin Tendulkar.

Tweeting for the Bollywood superstar on this auspicious day, Sachin wrote, "Happy birthday, @aamir_khan. You are a superstar and that's no secret... HaHaHa ???? Wish you the best always my friend." Sachin's tweet was a reference to Aamir's Secret Superstar, the musical drama film released in 2017.

Aamir had once revealed his fan moment with Sachin when the former India cricketer was cheering for him watching Lagaan movie. "To watch Sachin get engrossed in a match that I'm playing, and cheer for me, and all of that is so unreal to me. And what really is my most memorable Sachin moment. For the first and the last time, I guess I could see Sachin cheering for me, playing cricket. Something I'll never forget, it's etched in my memory."

Aamir celebrated his birthday with his wife Kiran Rao. He took a break from his Thugs of Hindostan shooting in Jodhpur (Rajasthan) and flew to Mumbai.

Other than Sachin, Suresh Raina and Harbhajan Singh also wished Aamir on his birthday.
