She may have to wear baggy scrubs for Grey's Anatomy, but Camilla Luddington (Jo Wilson) is still staying in tip-top shape this summer. As for how she does it?

"Been running this week back home in my new @nike #lunar running shoes. #obsessed #converted," she tweeted earlier in the week, along with a photo of her new kicks. If that's Camilla's secret, then we're going straight to the shoe store later tonight!

So we know Camilla is going to have a smokin’ bod on Season 10, but what will go down with her and Alex's (Justin Chambers) relationship? When asked if Alex and Jo were going to stay together, Camilla told Elle, “Honestly, I have no idea. I have absolutely no idea.”

What do you think Alex and Jo's fate is? Let us know in the comments!
