Shah Rukh Khan finds it tough to make friends

He may be one of Bollywood's most popular stars but for actor Shah Rukh Khan, fame hasn't really guaranteed him hundreds of friends.

"My wife says I don't have time for friends and that is true. It is difficult to make friends. I hardly have any," Khan told reporters at his Mumbai residence.

The actor, who turned 44 on Monday, said he only makes friends while filming a particular movie but then "moves on".

"We are all so busy working, you have friendships when you are working together and creating a product like a film together," he said.

"Then, you move on to the next product and you make new friends there."

But that doesn't mean Khan has no friends at all.

"I have a good relationship with those that I work with, maybe that is why they work with me," he said.

The actor, who has wrapped up shooting for director Karan Johar's "My Name is Khan" said 2009 had been a tough year for him after a shoulder injury kept him out of action for two months.

"I haven't earned much this year but I hope to catch up," he said.

Shah Rukh Khan Promises More Action For 2010

Bollywood superstar Shah Rukh Khan, who turned 44 Monday, spent some "quiet time with family and friends" on his birthday, putting behind a year of ups and downs and looking forward to a strong comeback.

This year had just one of his movie hitting the silver screen, but he said that he has more in his kitty for his fans for the next two years.

"I am a workaholic, but in the last year I couldn't do much due to my shoulder problem. My team Kolkata Knight Riders (KKR) didn't do too well and I shot for just one film 'My Name Is Khan'. My injury also pulled me down in terms of my endorsements, but I had time to introspect and spend a quieter time at home with my children," said Shah Rukh during a media event.

"I feel more energetic and happy now and totally ready for a comeback with many projects in the next two years after this one-year break," he added.

He had a "quiet time with his family and friends" on his birthday.

Shah Rukh was in the capital Sunday to kick off the Airtel Delhi Half Marathon and cheer and egg on the runners. Shah Rukh, who is coping from his shoulder surgery he underwent earlier this year, did not run for the marathon, but was a ‘cheerleader’. His mere presence was a source of inspiration for them.

He said: "Though I could not run this time because of my shoulder and knee injury, I'll try to be fit and run next year. Running is a spiritual experience." 2009 was bad for him in terms of IPL, as his KKR failed to showcase a good performance.

He also suffered mental abuse after being detained at Newark Airport in the US in August.

Otherwise, 2009 gave the actor many reasons to cheer as he became Dr Shah Rukh Khan when he was presented an honorary doctorate in arts and culture by the Bedfordshire University in London.

He was also bestowed with two honours by the South Korean government - an honorary belt in taekwondo and the title of an honorary ambassador for culture and tourism.

Shah Rukh even purchased a 20 million pound apartment in London.

Shah Rukh is eagerly waiting for the release of ‘My Name Is Khan’, ‘Happy New Year’ and ‘Don 2’.
