Wendell Pierce and Meghan Markle starred alongside each other as a father-daughter pair on Suits for seven years

Like many others in the U.K., Meghan Markle‘s former Suits costar Wendell Pierce is counting down the days until baby Sussex makes his or her highly-anticipated arrival!

The actor — who is currently working in London — shared his excitement about the royal baby in a tweet on Monday and sent his best wishes to Meghan, who was his Suits costar for seven years.

“It’s great to be living & working in London while the excitement builds around the Duchess of Sussex soon giving birth to her first child,” Pierce, 55, tweeted. “Meghan I’m very happy for you. Blessings.”

On the long-running legal drama, Meghan, 37, portrayed paralegal Rachel Zane while Pierce played her father Robert Zane. Meghan eventually departed from the show in April 2018 ahead of her wedding to Prince Harry.

While on the show together, Meghan and Pierce shared a close bond. Before going public with her romance, Meghan had only told a few of her closest friends, including Pierce, about Harry.

“She met this nice guy and we always talked about him in code really. You know, ‘How you doing?’ ‘Oh, I’m going to London, coming from London, whatever,’” Pierce told Harry Connick Jr. on an episode of Harry, according to Entertainment Weekly.

As soon as their engagement was announced in November 2017, her proud TV dad tweeted his excitement.

“Congratulations to my TV daughter Meghan Markle and Prince Harry on the news of their wedding engagement,” he wrote. “Harry you have her TV Father’s blessing. Robert Zane approves.”

Pierce also revealed that before Meghan made her official exit from the Suits set last year, they shared a quiet moment together.

“I had a really wonderful moment as we were coming to an end of her time on the show,” he said. “It was just she and I in the room and I said, ‘I know your life is going to change but always know, no matter where you are, I will always be your loving fake father.’”

As Meghan approaches the end of her pregnancy, she and Harry, 34, have been making the most of their final weeks as a twosome, including going on a recent mini-babymoon at Heckfield Place.

Earlier this month, PEOPLE confirmed that the royal couple officially moved out of their Kensington Palace home and into their new cottage in Windsor.

The pair have lived in Kensington Palace’s Nottingham Cottage since their engagement, but the two-bedroom home was never likely to be a long-term residence — especially once they had children.

With all the pressures that come with bringing a baby into the world, the parents-to-be are resolved to build a sanctuary for their little family, according to a source close to the couple.

“This is a very happy time for Meghan and Harry,” the source previously told PEOPLE. “This baby has brought them even closer.”
