I saw the same seen and notices that the piece of comb she rremoved was
remarkably rectangular in shape.  Reaching into a wild hive and{pulling
out something like that would be difficult.  More than likely the piece
was already sitting inside the hive, if it was one.
        It could have easily been a swarm, well fed, placed on the outside
of the tree.  She was wearing white.  This would have minimized her chance
of being stung.  Using a known gentle hive of bee on a bright sunny day
would make the stunt very safe.  It also helpes to be comfortable around bees.
She appeard to be calm.  So it worked.
        Ask the star if she got stung.
