Bollywood superstar, Shahrukh Khan has been hopping from one city to another promoting his latest flick RA.One. But for his 46th birthday on Wednesday, the actor says he wants some relaxed time with friends and family. “I am just really very tired. I have just come in from Toronto and LA. The race has exhausted me. So I am just going to go, hang out with my friends. I will be be in Mumbai with my friends and family,” SRK told reporters at the red carpet of the F1 after-party on Sunday. After multi-city promotions in Mumbai, New Delhi, Kolkata, Bhopal, Vadodara, Chennai and Bangalore, SRK went to Dubai, London, Toronto and Los Angeles. The exhaustion reflected in his eyes and in his voice too. Though he was excited about attending the F1 party where international pop star Lady Gaga performed, he was quite unsure of his own birthday bash. “I don’t know (whether I will throw a party or not)…let’s see,” he told. But Shahrukh’s wife Gauri has already begun calling in close friends for a small party. By the time the guest list is done, we wonder if it will still remain a small party or not! Incidentally, the birthday bash will also be combined with the success party of his ambitious superhero flick, RA.One.
