Meghan Markle has put the final touch on a new project after announcing she wasn't coming to the Coronation in the UK.
The Duchess of Sussex will stay in California with her children Archie and Lilibet.
Buckingham Palace said it was pleased to announce that Prince Harry will be there on May 6 for the historic event.
Harry, who laid bare his troubled relationship with the royal family in his controversial Netflix documentary and autobiography Spare, will be alongside other family members including his estranged brother Prince William and wife Kate.
The announcement now ends months of speculation about whether or not the couple would be at the Coronation, which falls on the same day as Archie's fourth birthday.
It comes at the same time that Meghan has successfully been given a trademark to relaunch her lifestyle website The Tig, The Sun Online reports.
Its logo has a handwritten Tig and a full stop at the end.
Meghan shut the blog down after she got engaged to Prince Harry in 2017.
At the time it is thought she was earning up to £60,000-a-year through advertising.
Yesterday, the Palace said in a statement: "Buckingham Palace is pleased to confirm that the Duke of Sussex will attend the Coronation Service at Westminster Abbey on 6th May.
"The Duchess of Sussex will remain in California with Prince Archie and Princess Lilibet."
Archewell, Harry and Meghan’s charitable foundation, issued a nearly identical statement to Buckingham Palace confirming the duke will join guests at the coronation.
A spokesperson said: "The Duke of Sussex will attend the coronation service at Westminster Abbey on May 6th. The Duchess of Sussex will remain in California with Prince Archie and Princess Lilibet."
It is said Archie's birthday has played a factor in the decision for Meghan to remain at home with her children - and it is expected Harry will make a whistle-stop trip to the UK for the big event.
It is reported that Archie and Lilibet were not formally invited to the event as organisers were waiting to hear if they would make the trip to the UK before devising any plans.
Meanwhile, sources told The Telegraph that Harry "would always regret it" if he didn't attend the Coronation and wanted to be there on the "biggest day" of his father's life.
Another friend told the publication Meghan considers her future to be in the US, with it also reported her appearance at the Coronation risked "overshadowing the event".
