Meghan Markle revealed baby son's name YEARS ago - and it's very unusual, royal fan claims
"I have to admit, I didn't believe it," he admitted. "We heard the rumours, I thought they were dating, I'm like ok sure. They were like, 'No, it's serious'. And I was like, 'Yeah right'.
"I was recurring [character], so I'd go back and forth. And I was like, 'Yeah, maybe, I don't know.'
"Then one day there was this very mysterious stern British security guy on set, real MI5 type. And I said, 'Oh, this is serious! This is real!'"
This comes after a royal fan claimed that Meghan revealed what she would name her baby son years ago - and it isn't exactly traditional.
Speculation has turned to what the happy couple will name their son, with the current bookie's favourite being Alexander .
But a royal fan appearing on This Morning today has claimed that Meghan previously spoke about what she wanted to call her son years ago.
Meghan Markle's son could be a Prince after all - but he'll have to wait a few years
Reporting from Windsor today on a bus of fans celebrating the royal birth, Alison Hammond asked one woman clad in union jack attire what she would call Meghan and Harry's son.
"Gray," fan Anita Atkinson replied firmly, leaving Alison bemused.
"Why?" Alison asked.
"Well that's what Meghan said a few years ago!" the woman replied indignantly. "She said if she ever had a baby she'd call it Gray!"
"Well I think we'd have fifty shades of opinion if that happened!" Alison exclaimed, laughing
Watching from the studio, hosts Phillip Schofield and Holly Willoughby raised their eyebrows at the suggestion.
"I love that intel, baby Gray," Holly mused. "How about that?"
"Price Gray," Phil remarked.
