Queen Letizia welcomed U.S. First Lady Michelle Obama to Madrid last week.
Mrs. Obama was on a tour of several countries to promote her Let Girls Learn initiative.
Queen Letizia, who has met Mrs. Obama several times before, spoke at the event, and then welcomed the first lady at the Zarzuela Palace complex.
It is notable that Queen Letizia did not take Mrs.Obama to the more formal areas of the sprawling complex.
Instead, the two walked the gardens of the secluded residence where the Queen and King Felipe live.
The Obamas are scheduled to visit Spain in the coming weeks.
