Selena Gomez Gushes Over Olivia Wilde's 'Booksmart' Movie at Big Slick Ten Event

Selena Gomez throws out a pitch during the Big Slick Ten Celebrity Weekend held at Kauffman Stadium on Friday (June 7) in Kansas City, Mo.

The 26-year-old entertainer was one of many celebs who made it out to the event to help raise funds and awareness to the Children’s Mercy Hospital.

At the game, Selena was seen chatting with Ariel Winter on the field, as well as her Fundamentals of Caring co-star Paul Rudd. She even met up with Katherine McNamara, who she snapped a photo with.

The next night, Selena joined Olivia Wilde and the two snapped a couple of really cute pics together.

“When Olivia is a star and Paul wears your face on a shirt (btw if you haven’t seen Olivia’s movie Booksmart I don’t understand you),” she captioned a set of photos.
