Prince Harry could not have looked any happier while visiting NAZ, a sexual health charity, in London on Tuesday. The young royal continued his bid to promote HIV awareness [1] by meeting with members of the Joyful Noise Choir and encouraging them to not be scared of the stigma attached to their disease [2]. Harry kept things casual for his visit, sporting a blue flannel shirt and the same beaded bracelet his girlfriend, Meghan Markle, has also been photographed wearing [3]. His latest appearance comes just a few days after Harry linked up with Princess Charlene of Monaco [4] at a rugby match between England and South Africa in London. It was also reported that Meghan paid him a short visit [5] over the weekend after she was spotted grocery shopping near Kensington Palace, so perhaps Meghan is the reason for his smile?
