After making a lovely arrival together, with the 26-year-old British actress giving a glimpse at her growing baby tum, they were seen shaking hands and chatting away with the royal couple.

William and Kate are the proud parents to two children of their own, Prince George - who turns one in two weeks - and Princess Charlotte, who was born in May.

So perhaps they were sharing parenting tips with Hollywood star Josh, 36, and Tamsin, who are about to become first-time parents.

They bore huge smiles on their faces as they conversed with the British royals, who had stolen the show on the day while watching Andy Murray take on Vasek Pospisil to fight for his place in the semi-finals.

It was revealed on Friday that Tamsin is pergnant with her first child, and the beauty was certainly glowing as she arrived at the tennis championships in SW19 earlier in the day.

The St. Trinians actress was accompanied by Josh, as they made their first public appearance together since the proud father-to-be made the announcement about the baby.

Tamsin opted for a sleeveless summer dress which flowed to just above her knees and she paired it with purple heels.

She wore her long blonde hair in a high ponytail and was fresh faced and glowing. 

Dapper Josh was clad in a dark suit with a blue shirt as they arrived at the oldest, and arguably most prestigious, tennis tournament in the world. 

Meanwhile, on Friday the Penny Dreadful actor's representative confirmed the English actress is pregnant with the couple's first child.

The representative told Page Six: 'It’s true and they are beyond thrilled.'

Look royal in red in Kate's L.K. Bennett dress

It's been a busy few days for the Duchess of Cambridge and her family.

It was her daughter's christening on Sunday and the rest of the Middletons have all managed to squeeze in a visit to Wimbledon. But now it's Kate's turn!

Of course, she looked as chic as ever for her day on Centre Court, shunning traditional tennis whites for a red dress. When teamed with an animal print Diane Von Furstenberg clutch bag and nude court heels, it's classic Kate with a twist.

The dress is from one her favorite brands, L.K. Bennett and we love the fit and flare shape. The midi skirt and elbow-length sleeves make it an elegant choice, and the bold hue will ensure she stands out from the crowd of spectators. Of course she'll be cheering on Andy Murray but the color is a nod to his Canadian opponent Vasek Pospisil too. Talk about dressing for the occasion!

And the best news is it's still in stock (for now...), so follow the link on the right to snap it up ASAP.

Just a few months ago, the 40 Days, 40 Nights star revealed he was looking forward to being a father.

He told Playboy: 'I have to get a car that's safe for my kid. I don't have a kid yet, but that's the idea coming into my head these days.'

The big baby news comes as it was revealed the Penny Dreadful actor sold his Minneapolis mansion for $2.3 million, according to the Minneapolis Star Tribune.

He had owned the historic, Victorian-style house for 13 years

While the actor lost money on the real estate deal, no doubt the funds will go towards a baby proof property now that they are expecting.
