However, the pair appeared to be ushered through a side entrance to the chapel – avoiding photographers.
Meghan wore a long blue coat for the occasion – which she kept buttoned up at the top.
And Australian fashion expert Donny Galella told New Idea the choice of outfit may be a sign that happy news is on the horizon
“Meghan is adding more fuel to baby rumours,” he told New Idea.
“That big coat could be hiding something? But she does look chic."
Fans of the royal couple also went into overdrive – speculating she is expecting.
“Something about Meghan's outfit choice makes me think she's pregnant and hiding a baby bump. It's so conservative,” wrote one fan on social media.
Another added: “I have a feeling that Meghan is pregnant...she’s glowing and her face looks fuller to me.. can’t wait for them to announce it.”
