Twitter is infectious and even Dilip Kumar couldn't stay away from it. The Thespian joined the micro-blogging site on his 89th birthday and Amitabh Bachchan is the first to welcome him.

Dilip Kumar's Twitter page is called "TheDilipKumar" and it became operational Sunday, which was his birthday.

"Thank you all of you who have made my simple life so rich with all your love," the legend said in his first tweet. "It is a true blessing to be so loved and a wonderful feeling to wake up and realise one is younger than was yesterday," he further posted.

Amitabh welcomed him saying, "Please welcome the Master, the Thespian, the Ultimate...Dilip Kumar, Dilip Saheb, Yusuf Khan on twitter....ID:@thedilipkumar."

On his birthday, Bollywood celebrities like Deepa Mehta, Shabana Azmi, Javed Akhtar, Farhan Akhtar and Amitabh Bachchan tweeted and showered their love on Dilip Kumar and wished him good health and long life.
