The How I Met Your Mother stars were visited today on set by Olympic athlete McKayla Maroney! See the pictures they posted online.

Both Alyson Hannigan and Neil Patrick Harris have tweeted images of the 16-year-old gymnast, who won gold in the team competition and silver in the vault for America at this year’s Olympic Games:

Earlier this month, stars of The Vampire Diaries made a video showing support for another young gymnast competing for the U.S., Gabrielle Douglas. It’s great to see these stars engaging with the athletes!
