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.

After defending Katrina Kaif in his previous tweets, Salman Khan decided to promote his Being Human merchandise, which were on sale online.

'Haan yaar ! U will get the delivery any whr , obviously na , kamaal karte ho yaar pandey ji. Hello guy's ! V touched but don't jam the server na hahaha thank u .god forbid if any defect replacement is immediate not repair,' he tweeted.

He adds that he is not earning anything from the sales. 'I vil tell u wat the funda is that charity is 76% the rest is watchmaker. Trying to get his percentage down so more goes to charity. How do watchmakers deal they have cofficent of 7 That is if u buy a watch its 7 times goes to owners pocket. Kaun hai woh,' he tweeted.

The merchandise includes watches, clothing and accessories. And like Salman says, 'Mey toh bartan or choley,chuley bhi bechuaga Lena hai lo nahi lena toh...hehehe.'

Amitabh Bachchan never seems to be happy with his performances. He informs: 'Back from another grueling day .. why do I always feel there was room for better work ? So frustrating .. but director says fine so.'

He also tweeted about his gym-action with Saif Ali Khan. 'Early morning was back in gym .. and feels good that I did go .. more flexible, relaxed and energized ... Saif too at gym .. Shoots moving at a pace which is ahead of schedule .. thank god ..atmosphere and ease of work condition is responsible for it !!' he tweeted.

Meanwhile, film writer Mushtaq Shiekh posted a picture of him and Shah Rukh Khan after winding up work: 'Spend 48 hrs with @iamsrk shooting. he refuses to get tired. ZKJ, Don, press meets. I crashed out-he went to work!'
