The 'Fifty Shades of Grey' star's wife, who gave birth to their daughter, Dulcie, while he was shooting the film in Vancouver in November 2013, was seen strolling around London with the actor with a noticeable baby bump on Friday (20.11.15), according to E! News.

The brunette beauty first sparked speculation she is pregnant again in September.

The notoriously private couple, who waited until one month after Dulcie was born to announce her arrival, have yet to officially confirm the happy news.

Jamie, who was previously in a long-term relationship with actress Keira Knightley, recently admitted he was smitten with singer Amelia, 33, "from the start" and loves being a father.

When asked if there was anything about his wife that irritated him, the 33-year-old heartthrob said: "I was smitten from the start, I really was. I'm more in love with her today than I was at the start, so no.

"She's dream stuff. It's amazing.

"I love fatherhood. These last couple of years have been quite something. But we're enjoying it."

Amelia previously dated Irish actor Colin Farrell.
