Tom Hardy and his actress wife Charlotte Riley are reportedly expecting their second child.

The pregnancy rumors emerge days after Charlotte, 36, attended the London premiere of her new film, Swimming With Men, wearing a loose-fitting white Oscar de la Renta gown, which hid her figure.

She was accompanied to the event by Tom, who opted for a more casual white T-shirt, jeans, and sneakers look, topped off with a leather jacket.

The fiercely-private couple, which met while filming a TV adaption of Wuthering Heights in 2009 and wed in secret in 2014, has yet to comment on the baby claims, which were first reported by The Mail on Sunday.

The stars already have one child together, but they didn't announce the pregnancy news until the Peaky Blinders actress was nearing the end of her third trimester, as she showed off her big bump in a fitted black dress at the premiere of Tom's Kray brothers biopic, Legend, in London in September, 2015.

Their child was born in late October, 2015, but they have never confirmed the name or gender of the tot.

The Dark Knight Rises actor, 40, also has a 10-year-old son named Louis, from his relationship with assistant director Rachael Speed, while he was previously married to producer Sarah Ward from 1999 until 2004.

While Hardy likes to keep his personal life private, in a rare candid chat with GQ magazine in early 2015, he admitted fatherhood had changed him for the better.

"There's such a blissful sense of otherness that I can't remember what it was like to not have children," he shared. "I used to think a lot about myself. I still do, I guess. I mean, I have the capacity to indulge in myself.

"My primary relationship was with myself, and that was interrupted irrevocably when I found out I was going to be a father. It cut out so much s**t from my head. There was the idea that in order to look after someone else, you must first truly look after yourself. I need to be fit and good to go and get s**t done."

"I was healthy and already had a lot of s**t behind me – rehab and all that – but I didn't have an anchor," he continued. "A child is an anchor. And it gets heavy. Is your son going to be a reflection of you? Fear of becoming your father. And then the fear of not becoming your father. All of these conversations which were nice to think about and hypothesize about before are now immediately connected… You can't un-have a son."
