The Audience Is The Real Star.
It's one of those unusual situations in which the audience members are more interested in watching than the celebrities performing on stage. It is accurate to say that Matt Smith and Karen Gillan from Doctor Who are photobombing a guy while he is asking his fiancée to marry him.
The renowned individuals are thrilled to be able to share this experience with their followers, and the two people who are listening to them don't seem to be troubled by the fact that they are talking about one of the most significant events in their lives with strangers. The performers' presence transformed the event's nature into something new and exciting.
