India, Oct. 15 -- Actor Jack Black couldn't resist adding comic flair to Naomi Watts' big moment. At Naomi's Hollywood Walk of Fame star unveiling on Monday, the actors made headlines with their viral photogram - him lying across her freshly unveiled star and her in stitches behind him. Jack (56) and Naomi (57) have previously shared the screen in King Kong (2005). The ceremony was attended by Naomi's husband Billy Crudup, son Sasha Schreiber, and actors Ed Norton, Ryan Murphy, Sarah Paulson, and Kyle MacLachlan. For her part, Naomi was visibly moved, a mix of disbelief and gratitude. "I can't believe it," she told Variety, adding, "I have all kinds of imposter syndrome. I've always felt like I'm supposed to struggle, I'm supposed to keep proving myself, and this came out of the blue. It's really lovely."htc...
