The expert, Daniela Elser, expressed her concerns about the couple's impact on the royal family, saying that it would be hard for anyone to pay attention to King Charles and Queen Camilla during their first month on the throne with the camera-ready Duchess back in the public eye.
As Elser pointed out, the Sussexes have a tendency to dominate the media when they make appearances, drawing attention away from other members of the royal family.
Elser's comparison of the couple to blackholes implies that they have a powerful gravitational pull that draws in all the attention and leaves little for others.
It remains to be seen how the couple's high-profile public appearances will impact the future of the royal family.
