• Jennifer Garner just showed off her ballet skillson a moving airport walkway.
  • She's a ballet superfan and especially loves the American Ballet Theater.
  • In her post, she also sent "healing love" to Misty Copeland, who was recently injured.

Ballet superfan Jennifer Garner doesn't waste an opportunity to show off her dance moves . On one of the moving walkways at the San Francisco International Airport, the 47-year-old actress practiced some of the skills she's learned from her ballet-inspired dance workouts. Other travelers were a little confused (which, fair), but Jen didn't seem to care.

"Ive been working on my #Giselle. Is this right, Cindy?" she captioned the post. "Thinking of all of you at @abtofficial. Sending healing love to @mistyonpointe. Merde to @isabellaboylston, @stellaabreradetsky, @skylarbrandt, @heeseoabt, @gillianemurphy, @sarahlaneofficial AND everyone else! (Hi, @jamesbwhiteside)."

Clearly, Jen follows ballet closely, like some people follow baseball. Case in point(e): Her shoutout to ABT principal dancer Misty Copeland, who announced yesterday that she would not be dancing the role of Giselle with the American Ballet Theater (ABT) at the Kennedy Center, citing an unspecified injury. "Im going to be fine, but as dancers, we have to listen when our bodies speak to us," she said on Instagram . Instead, dancer Skylar Brandt made her debut in the performance Thursday night.

Jennifer has long been a supporter of ABTyou may remember her hilarious Nutcracker video in December , where she dressed up as a Nutcracker and hyped up the cast before their Southern California performanceand often shouts out her favorite dancers on the 'gram.

In the comment section of Jen's airport video, ABT dancer James Whiteside wrote, "Hey Cindy! Thats absolutely what moving walkways are for. Youre the best." The Peppermint star even received an invitation from Julie Kent, the artistic director of the Washington Ballet, to stop by next time she's in D.C.

Oh, and btw, this isn't the first time Jen has showed off some unexpected skills this week. On February 12, Jennifer posted her impressive jump rope workout , where she successfully completed the dreaded double-under, to which ABT dancer Isabella Boylston wrote, "Nice ups!! Get after it, Cindy! ."

You might be wondering who Cindy is, since this mysterious lady shows up in a handful of Jen's ballet posts. "Cindy" is an inside joke between principal dancers James Whiteside and Isabella Boylston, who call each other Cindy. Based on James' comment to Jennifer, it seems like she is the third Cindy .
