On January 10, actor Hrithik Roshan will turn 39. And like every year, his wife Sussanne has something special planned for him this time too. However, she will get some help from Hrithik’s close friends, actor Arjun Rampal and his wife Mehr Jesia.A source close to the family says, “A big party is currently being planned. Every year, all of Hrithik’s friends from the industry are invited and the party usually goes on till the wee hours of the morning. His family (dad Rakesh Roshan, mother Pinky and sister Sunaina) will also be around. Sussanne personally looks into everything, so it’s a big relief for her to have Arjun and Mehr to help her out.”So far, a large menu consisting of a lavish spread as well as assorted beverages has been shortlisted. Sussanne, who is a professional interior designer, is very specific about the decor and therefore is looking into all the details of the party’s look herself. The get-together will be held at Hrithik’s house in Juhu.“Many A-listers from the industry are expected at the party,” says the source.
