The twitter world is quite a busy one, and Bollywood contributes a great deal to it. Here's looking at the best star tweets of the day.

Bipasha Basu insists that she's not a pampered celebrity. The picture she posted on twitter though, seemed to go against her claims.

'I need to learn to tie shoe laces asap! Embarassed that I can't! No patience grrrrr! Promise I am not spoilt! Will learn soon,' Bipasha tweeted.

She added that the girls in the picture weren't child labourers! 'Well the ppl helping me in the pix r my friend n sister,Who I help often with the same!So am sorry if it hurt anyones sentiments!' she tweeted.

Amitabh Bachchan, who is busy shooting for Prakash Jha's Aakarshan in Bhopal, will be co-starring with Hema Malini yet again.

He informed: 'Really fagged out now ...ready to pass out .. more tomorrow .. with renewed vigor and energy .. good night dear.. love to you. Hema ji joins us tomorrow for the shooting of 'Aarakshan' .. a cameo but all looking forward to her arrival ... 'Baghbaan' remembered.'
