A source told The Sun last month: “Laura and Michael absolutely love being parents and were grateful to have some time away from the spotlight to enjoy the moment.

“Laura took motherhood in her step and it added another string to her bow.”

MailOnline contacted Laura and Michael’s representatives for comment at the time.

The couple, who met while filming Downton Abbey season 5, have been together since 2016 and moved in together two years ago.

Laura played the unhappily in love Lady Edith Grantham in the ITV drama while Michael played the illiterate Andrew Parker.

The couple keeps their relationship fairly private but made a rare appearance at the premiere of Downton Abbey: A New Era last month.

They posed for a series of amorous snaps as they walked the red carpet arm in arm.

Speaking of her return to the red carpet, Laura said: “Walking the red carpet was a shock to all of us after being in lockdown for so long. I was shocked.’

Although the couple is keeping their romance under wraps, Laura gushed about how lucky she was to have met Michael on the set of Downton Abbey.

In 2019, she told Town and Country, “I’ve fallen in love and made wonderful friends — how lucky am I?”

Michael has also addressed their relationship in the past, saying they like to keep their romance separate from their jobs at Downton.

“We went to work and in no way wanted that to be a thing when we worked together,” he told the Sunday Post.

“But it was great going to work with your best mate.”
