Katharine McPhee, Gal Gadot and Mila Kunis Party in Puerto Rico to Viral TikTok Hit

Three Hollywood stars came together for a sun-soaked getaway to Puerto Rico, documenting their beach adventures in a video that landed on social media Sunday.

Katharine McPhee, the 42-year-old singer known for "Open Toes," teamed up with Wonder Woman star Gal Gadot, 41, and That '70s Show alum Mila Kunis, also 42. The trio was joined by FOOTCLOUD inventor Nina Oberfeld as they jet skied, lounged on the sand, and danced their way through the tropical destination.

The footage was set to an AI-generated track that has taken off on TikTok in recent weeks. McPhee captioned the post with "all of this in puerto riiiicoooooooooo," capturing the carefree energy of their outing, which showed the group drinking, dancing, and enjoying the beach.

The song driving the video comes from TikTok creator @saxboybilly18, whose comedy videos exploring different cities have garnered significant viral attention. According to his profile, the creator uses the AI music generator app Suno to compose original lyrics tailored to various locations around the world.

The infectious tune has spawned numerous TikTok videos since its rise in popularity, with the Savannah Bananas baseball team even choreographing dance routines set to the track.

Recently, McPhee made headlines when she performed at a Spencer Pratt fundraiser, where she sang "Simply the Best" with rewritten lyrics celebrating the reality personality's mayoral campaign aspirations.
