AceShowbiz - Prince Harry's brief appearance at his father King Charles' coronation still sparks chatter among many people. In a new interview, royal commentator and biographer Angela Levin blasted the Duke of Sussex by saying that he acted like a "silly teenager" at the Saturday, May 6 event.

"I think he was very, very uncomfortable, I think he felt very strange that he was there by himself," she told Sky News host Paul Murray of Harry, who was seated at the third row during the ceremony, away from his brother Prince William. "Rushing off immediately without even having the time to say congratulations to his father and his brother is just hopeless really."

Harry did leave Westminster Abbey as soon as the ceremony ended. The father of two headed to the Heathrow airport right away as he wanted to arrive in the U.S. in time for his son Prince Archie's fourth birthday, which also fell on May 6.

In related news, Prince Harry appeared to address his wife Meghan Markle's absence in a video from the historic event. According to The Mirror, a lip reader picked up on the moment where the Duke spoke about his wife to Princess Eugenie's husband Jack Brooksbank as they waited for Charles to arrive.

The expert suggested that Harry responded to Jack's unknown question by saying, "No, she's at…." Jack, meanwhile, was believed to have told Harry, "If it makes [you] feel any better even I can do it. It's not quite the life, is it?"

"I haven't had time for that, not if it's over…," Harry allegedly said while shaking his head. Harry later seemed to make a very cryptic remark, stating, "It's an eventuality."

The lip reader additionally claimed that Jack asked Harry about "the meeting," though it's unknown what he was referring to. Harry later told him, "It's sad. I'm fed up, I've tried talking to him."
