Jamie Lynn Spears To Compete In Celebrity Softball Game

Jamie Lynn Spears is going from the small screen to the big diamond — at least for one day — ’cause the actress is gearing up to compete in a charity softball game on Saturday.

Britney‘s little sister is slated to field ground balls and take hacks at the plate at the University of Louisiana Monroe … in an effort to help the school’s softball team raise funds.

It’ll all go down at 6:30 PM — and general admission tickets start at $40 … but for an extra $20, university officials say you can get an autograph from her following the game.

Jamie said in a statement she signed on for the event in part because of her daughter, Maddie, who’s an up-and-coming star in the sport.

“I’m raising a young female athlete,” she said, “so I’m honored to be asked to participate in an event to raise money for other female athletes.”

The “Zoey 101” star — who’s most recently been in “Sweet Magnolias” — told Extra Inning Softball she’s taking things pretty seriously … training with Maddie so she can impress at the dish.

Maddie’s a pretty good coach for JLS to learn from … take a look at one of her home runs that Jamie Lynn recently posted — she’s got a swing!
