The stars were out in full force for last night's 2012 Concert for the Rainforest Fund at Carnegie Hall in NYC.

Sting's wife, Trudie Styler, co-founded the Rainforest Fund to protect land and human rights in the Amazon rainforest, and the two-hour charity event brought out stars like Elton John, Channing Tatum, Jenna Dewan, Meryl Streep, Jennifer Hudson, Bruno Mars and so many more.

Even President Bill Clinton spoke about this noble cause.

The antics were all over the place, from a striptease courtesy of Elton and Channing to a fabulous duet from Jennifer and Bruno. Even a take on The Wizard of Oz with Meryl, Elton and Sting. Check out all the fun pics!
