Superstar Aamir Khan won't celebrate his 45th birthday Sunday.

"I will not be celebrating my birthday this year, " Aamir told over e-mail from Mumbai.

Media reports said the actor will fly to the capital Sunday to rub shoulders with acclaimed Hollywood filmmaker James Cameron and to discuss the future of cinema.

"Yes, I am going to be in Delhi for (a) conclave where I would be meeting Cameron, " said the actor.

Aamir did not say why he won't celebrate his birthday. But a source close to him said: "He in any case doesn't believe in parties and celebrations for his birthday. Moreover, with his dad (noted filmmaker Tahir Hussain) passing away last month, he is keeping a very low profile."

Incidentally, his colleague Shah Rukh Khan has teamed up with international rapper Akon in Mumbai to record a song.

With cinema in his blood, perfection in his attitude and known as the king of promotional strategies, Aamir managed to deliver several super hits since his first success "Qayamat Se Qayamat Tak" (1988).

In more than than two decades he has given hits like "Dil", "Dil Hai Ki Manta Nahin", "Jo Jeeta Wohi Sikandar", "Rangeela", "Raja Hindustani", "Ishq", "Ghulam", "Sarfarosh", "Dil Chahta Hai" and "Rang De Basanti".

His 2001 hit period drama "Lagaan" was nominated in the best foreign picture category at the Oscars.

Off late he struck gold with his 'one-year-one-movie' startegy. His "3 Idiots" and "Ghajini" smashed all box office records to become Hindi cinema's top two highest earners till date. They have reportedly collected Rs.400 crore and Rs.226 worldwide respectively.

But Aamir is not beaming.

"I don't have any recipe (for success). Lot of us often forget that the business we are in by definition is basically selling stories... We have to be different each time. I have to reinvent myself... that's the demand of my job, " Aamir had earlier said.

"I am attracted to scripts that move me emotionally and when you have such stories to tell, it doesn't matter how unusual it is, people connect to it... I've no idea what audiences want. I only have an idea about what I want..., " he added.

Aamir is a winner of Padma Bhushan, the nation's third highest civilian honour.

Recently, the actor reportedly bagged the biggest endorsement deal by inking an agreement with new telecom entrant, UAE's Etisalat, for Rs.300-350 million for three years.

With so many feathers in his cap, the actor stands tall as an epitome of commercial cinema.

But he is now taking a sabbatical from acting to concentrate on his production ventures - "Delhi Belly", "Peepli Live" and his wife Kiran Rao's directorial debut "Dhobi Ghat".
