Well, at least their behavior at a recent wedding did lead to such doubts.Apparently, both Siddharth and Samantha attended the wedding of Sid’s close friend on Friday. Dressed in beautiful traditional white attire, the twosome behaved like a couple and stood by the bride and groom all through the rituals.It is now believed that the couple is trying to hide the news as Samantha is at the peak of her career and the market for a married actress is much lesser compared to an unmarried star.
