Donnie Wahlberg

As it turns out, when you're performing at Hersheypark Arena, you're probably going to spend the day prior riding roller coasters.

Or, at least, that's what Donnie Wahlberg of New Kids on the Block (NKOTB) did.

Before the Saturday night show, Wahlberg held an impromptu dance session in the park, posting his moves to Instagram.

One fan, user Carolina2676, spotted him riding a roller coaster, offering him a pep talk before the ride shot off.

NKOTB headlined the Mixtape festival, which also featured the likes of Debbie Gibson, Salt-N-Pepa, Naughty by Nature and Tiffany.

The concert even featured some Lancaster talent, as the Lancaster Athletic Cheer squad performed alongside NKOTB.
