Prince Harry and Meghan Markle visited Prince Charles and Camilla, Duchess of Cornwall, at Clarence House yesterday after attending the Queen's Thanksgiving service at St. Paul's Cathedral, OK! reported in the Daily Express.

The visit took place shortly after the Duke and Duchess of Sussex attended a church service and did not publicly interact with either Prince Charles and wife Camilla or Prince William and Kate Middleton. The Sussexes sat in the second row next to Princess Beatrice and her husband Edoardo Mapelli Mozzi and Princess Eugenie and her husband Jack Brooksbank, while behind Prince Edward sat Sophie, Countess of Wessex, and their children, Lady Louise and James, Viscount Severn. Across the aisle in the front row were more senior royals, including Prince Charles and his wife Camilla and Prince William and his wife Kate.

According to "OK!", Harry and Meghan chose to miss the reception after the church service at the Guildhall, presumably to make plans for their daughter Rivette Diana, whose first birthday is today.

At some point, the Sussexes went to the Clarence House to talk to Charles and Camilla. After Harry and Meghan were evicted, Charles and Camilla also left the London house.

It remains unclear whether Harry and Meghan interacted with William and Kate at all this week, as they have been keeping a low profile. Since arriving in the UK earlier this week, we have seen the Sussexes attending Trooping the Colour and watching the festivities from the Major General's office with other members of the royal family. The Queen also reportedly met her namesake, Lilibet, in Windsor that evening. We have not seen Harry and Meghan since the Thanksgiving Day service, as they were preparing for today, Lilibet's first birthday.

We know that William and Kate will not be attending Lili's birthday celebration due to a planned visit to Wales.

"At the moment, it looks like Harry and Meghan and William and Kate will not be meeting separately during the Jubilee celebrations," a source told Page Six of OK! 'So far, there is nothing in their diaries.'
