Meghan Markle not only showed PDA with Prince Harry at Prince Charles' garden party on Tuesday, she also showed how she's getting along with her royal in-laws. The new Duchess of Sussex shared some laughs with the Prince of Wales and the Duchess of Cornwall while her husband gave a speech, but she and Camilla Parker Bowles also had some sweet moments on their own.

Royal fans on Twitter spotted Markle and Harry's stepmom holding hands during the Buckingham Palace celebration, thanks to a photo taken by Daily Mirror's Ian Vogler. Others got enthusiastic when the duchesses exchanged a kiss goodbye.

It's possible the hand-holding was taken from this longer encounter.

Some eagle-eyed viewers also noticed Camilla even motioned to Meghan to move in closer to her and Charles when Harry stepped to the podium.

Lovely help for Meghan from the Duchess of Cornwall at the end! https://t.co/3vjdMGI3RD - Christin Zi (@PackhamGown) May 22, 2018

Others simply gushed over the Duchess and Prince Charles welcoming their new daughter-in-law into the family.

The queen has the most beautiful grand daughters in law. And I think the Prince and Camilla truly love Meghan. Who couldn't love Meghan though? 💓 - Jennifer Tibbs (@jdwest72) May 22, 2018

It is just really nice to see how welcoming they've all been to Meghan, and she looks like she fits right in with the family and I'm still really emotional from the wedding and I don't know what is going on with me anymore - Marie (@MyQueenTroian) May 22, 2018

Duchess Camilla-who wed Prince Charles in 2005, eight years after he divorced Princess Diana-had an enthusiastic (albeit odd) reaction to Harry and Meghan's engagement in November.

She said she was "absolutely thrilled" over the "brilliant" news. She added, per People, "America’s loss is our gain. We are all absolutely delighted. As you can see, they’re so happy. Sometimes in a climate where we’re surrounded by a lot of bad news, it’s a real joy to have a bit of good news for once."

Harry believes that if his birth mother, Princess Diana, were still alive, she'd be close with Meghan too. They "would have been thick as thieves, without question," he said in his post-engagement interview with Markle. "I think she would just be over the moon, jumping up and down, so excited for me, but then would've also probably been best friends with Meghan."

Although Princess Diana couldn't be present at their wedding, the couple still paid homage to her by having her sister, Lady Jane Fellowes, do a reading; including her favorite flower, forget-me-nots, in the bridal bouquet; and letting Meghan wear her aquamarine cocktail ring to the reception.

"It is days like today when I really miss having her around and miss being able to share the happy news," Prince Harry said of his late mother after announcing his engagement to Markle in November. "I'm sure she's with us, jumping up and down somewhere else," he added.

We have no doubt he felt the same way on his wedding day.
