Lady GaGa will "hatch out of an egg" at the start of shows on her 'Monster Ball' tour.

The eccentric 'Poker Face' singer has said her tour - which replaces the cancelled 'Fame Kills' tour, which she was preparing to co-headline with Kanye West - will show an "evolution" of her character from the very beginning.

She told Dallas radio station KISS 106.1: "I actually hatch out of an egg in the show. That's the beginning of the show. It's kind of the beginning of evolution. I begin as a cell."

"The show is based on this theme of evolution, which has a lot to do with how I've changed over the years, and in a symbolic way of describing myself as a person, as Gaga."

Gaga also said her 'evolution' concept is a subtle message conveying her thoughts on "pre-packaged" pop stars, who haven't had to work hard in the same way as her to make it famous.

She added: "In a way, I think it's kind of convoluted the way that people think about it, because the assumption is that they believe that pop singers should kind of pop out of nowhere and be born and cracked out of an egg one year that the record label lays, and that's not the way that should happen."
