Lady Gaga and Elton John will reunite

Lady Gaga and Elton John will reunite on stage for the first time since they performed together during Gaga’s opening show at the Grammy Awards.

This time around, the two will perform at the semi-annual Rainforest Fund benefit concert, a cause close to Sting’s heart. The fund will celebrate its 21st birthday at the world renowned Carnegie Hall followed by a gala dinner.

Sting and his wife, Trudie Styler started the charitable rainforest foundation in 1989. It has raised $30 million so far for rainforest conservation.

Trudie Styler says, "When Sting and I first visited the rainforest in Brazil around 21 years ago we observed first hand the destruction to one of the world’s most precious resources and knew we had to do something."

The couple also invited Shirley Bassey to perform. She is best known for her recording of three James Bond theme songs, Goldfinger, Diamonds Are Forever and Moonraker.

According to one rumour, all four stars will converge on the stage at one point to sing a rendition of the song Hey Big Spender.
