My ego gets out of control, says Madonna

Pop sensation Madonna says sometimes her ego gets out of control and it makes her a difficult person to work with.
The "Hung Up" hitmaker said this nature has got to do with her zodiac sign, reported Female First.
"I know that I can be difficult and demanding and push you, and sometimes my ego is out of control but I am a Leo," Madonna said in the a preview clip from her 'Madonna: Rebel Heart Tour'.
The 58-year-old singer previously compared herself to renowned artist Picasso.
"I like to compare myself to other kinds of artists like Picasso. He kept painting and painting until the day he died. Why? Because I guess he felt inspired to do so.

"Life inspired him, so he had to keep expressing himself, and that's how I feel ... I don't think there's a time, a date, an expiration date for being creative. I think you go until you don't have any more to say," she said.
