The Duke and Duchess of Sussex are reported to be in Rome, ready to attend the wedding of Meghan’s friend Misha Nonoo.
Harry and Meghan are said to have travelled without baby Archie Mountbatten-Windsor.
Designer Nonoo, who collaborated with the duchess on her Smart Set capsule wardrobe for the Smart Works charity, is preparing to marry oil tycoon Michael Hess.
Nonoo is credited with introducing American former actress Meghan to Harry after setting them up on a blind date in 2016.
Princesses Beatrice and Eugenie are also expected at the star-studded nuptials in Italy, along with Katy Perry and Orlando Bloom.
Buckingham Palace declined to comment.
