The royal couple said via Kensington Palace representatives, "We are very excited for Harry and Meghan. It has been wonderful getting to know Meghan and to see how happy she and Harry are together."
While they haven't been spotted publicly, Meghan has spent time with William and Kate during numerous trips to England to visit Harry. She also reportedly met the Queen who gave Harry her approval to propose.
It's unclear at this time whether Meghan will make Kate one of her bridesmaids, or what role she might have in the forthcoming wedding.
