Salman Khan had a BIG birthday bash to bring in his 50th birthday at his Panvel farmhouse. Celebrities drove down in hordes to wish him. There was even a surprise video shown at the event with messages from Shah Rukh Khan and his co-stars like Sonam Kapoor and Sonakshi Sinha. However, one video that never made it to the big screen was of his alleged girlfriend Iulia Vantur singing a special birthday song for him.
