LAS VEGAS (KLAS) — Katy Perry is thanking some caregivers at Sunrise Hospital & Medical Center with tickets to her show as part of a campaign to show appreciation for their hard work.

In a reveal set up to surprise “a handful of caregivers,” Perry’s video message was shown at 9:30 a.m. on Valentine’s Day.

“I just wanted to say thank you so, so much for everything you’ve been doing, and have done,” Perry said before telling employees they were invited to her show at Resorts World.

“You’re going to have a great time. You might even want to bring an IV bag for afterwards,” Perry said.

The “Frontline Valentine” program is an effort by Musicians On Call to thank caregivers. Artists including Dolly Parton, CeCe Winans, Aloe Blacc and Ingrid Michaelson are participating.

Perry’s “Play” residency at Resorts World runs March 2-19 and May 27-Aug. 13.

Musicians On Call, a nonprofit that brings live and recorded music to the bedsides of patients in healthcare facilities, is teaming up with the artists “to show love in hospitals this Valentine’s Day.”

In addition to Perry’s video message, the caregivers will also get a styling session at the local store of national jewelry brand Kendra Scott, which is providing 100 jewelry pieces for staff at Sunrise.
