Eco-conscious stars like Katharine McPhee, Amanda Seyfried, and Kristen Bell are pros when it comes to performing professionally, but they’ll also sing their hearts out for a good cause. The trio and other stars were on hand Monday night at A Concert for Our Oceans, a live musical event at the Wallis Annenberg Center of Performing Arts in Beverly Hills, Calif., to benefit Oceana, an organization that focuses on ocean conservation.

McPhee, who rocked a printed For Love & Lemons minidress and Alexandre Birman stilettos to the event, said she first became passionate about the organization after attending one of their events years ago. “I remember it being such an amazing organization that does so much for our environment and wildlife and our oceans,” she told reporters, before slaying her soulful performance of “Heart Shaped Wreckage” during the concert.

January Jones was there to support Oceana (but didn’t perform), as was her Last Man Standing co-star Mary Steenburgen, who performed an original love song, “I Choose You,” that she wrote for her hubby, Ted Danson. “She’s nervous about singing and playing the accordion, but I’m so excited,” Jones, who rocked a black lace Zimmermann dress and red Nicholas Kirkwood heels told reporters.

After celebs and guests enjoyed a cocktail reception complete with mini lobster tacos and barbeque chicken pizzas, Seth MacFarlane kicked off the show looking dapper in a black suit with plenty of jokes to boot. As he introduced Bell, who performed “Do You Want to Build a Snowman” and “Somewhere Over the Rainbow” in a flowy printed Etro dress, he said, “You probably know her best from the YouTube video of her crying about a sloth.”

Meanwhile, Kesha (above) also hit the stage, performing “God Only Knows” in a sheer Saint Laurent black top covered with silver stars, and Seyfried rounded up the show with performances of "Mean Ol' Moon" and "When It Don't Come Easy,” which she sang sitting on a stool with her hair pulled back in an effortless ponytail.
