Everyone who’s anyone in the world of music made sure to make an appearance at the 2013 Coachella Festival — and our favorite American Idol stars were certainly no different!

On Sunday, April 14, Season 5 runner-up Katharine McPhee soaked up some fun and sun while attending the Guess hotel pool party at the Viceroy Palm Springs. Chatting with fellow celebs such as Pretty Little Liars actress Ashley Benson and Guess model Gigi Hadid, the current Smash star sipped on drinks while showing off her amazing body in a tiny black bikini.

The 29-year-old singer/actress clearly had an amazing time at this year’s event, as she took to Twitter to share her disappointment that the party had ended. “Dear #Coachella, I'm in love with you. Why must you make me wait so long till next year? Sigh. Love, Your new fan.”

Katharine must indeed wait another year to return to the festival, but she’s got all summer long to show off those phenomenal abs!
