Was it something he said? British radio host Simon Mayo was in the middle of an interview with Naomi Watts on Tuesday, Sept. 3, when -- according to his Twitter account -- the actress cut the chat short and left. Mayo, who co-hosts the BBC Radio 5 Live show Kermode and Mayo's Film Review, claims he has no idea what upset the Oscar-nominated star, who was there to promote her new Princess Diana biopic, Diana.
"A first for me and @wittertainment as Naomi Watts walked out of an interview!" he tweeted to his 162,000 followers. "She seemed a tad uncomfortable with the questions. Shame."
Later, responding to journalist Shelagh Fogarty's question about what he had said to set her off, he wrote: "The honest answer is I have no idea. You know my hectoring style is always a problem."
"Did you suggest film might not be in best possible taste?" Telegraph columnist Allison Pearson inquired. (Pearson interviewed Watts after the Mayo sit-down and tweeted that the Aussie actress "was heavily guarded" with her responses.)
"No, not at all," Mayo replied. "Didn't express any opinion. So still baffled."
Watts, for her part, has yet to acknowledge the incident. However, she has admitted in recent interviews that she's somewhat anxious about how Diana will be received -- particularly by the late princess' two sons, Prince William and Prince Harry.
"I turned [the part] down twice," she confessed in an interview with the U.K.'s Sunday Times. "The biggest reason that made me pause was how the princes were going to be feel about this."
"I do care deeply about how the princes feel, of course," she said. "I am a mum of two boys. But it was a story that was bound to be told at some point, and it's possibly fresher than people expected."
