Selena looked absolutely adorable at Friday's celebrity softball game at Kansas City Royals' Kauffman Stadium. She was all smiles as she hit a fly to left, arrived safely at first and took selfies throughout the game.

She even got teammates Paul, Jason, James Van Der Beek, Chris Daughtry and Johnny Knoxville to give a shout out to her "Selenators."

The baseball field may be Selena's new happy place -- after the game, she tweeted, "Today was a good day!!" Double exclamation points are always a good sign!

Before continuing the charitable festivities on Saturday -- bowling and bocce were the big events scheduled for day two -- the visiting celebs goofed around and met some of the kids getting treatment at Children’s Mercy.

Olivia looked equally as sweet when she gave hubby Jason a quick kiss mid-festivities.

Talk about a fun day for everyone in Kansas City!
