Lady Gaga will open Warsaw's National Stadium with a concert on January 29th in Poland.
The stadium holds 58,000 people and cost around $730m to build. Gaga will officially open the stadium with a number of songs from her album 'Born This Way'. 

 Madonna has dropped allegations that Lady Gaga's multi-chart topping single 'Born This Way' used the chords from her song 'Express Yourself'.

In an interview with Newsweek, Madonna said "I thought, this is a wonderful way to redo my song. I mean, I recognised the chord changes. I thought it was... interesting."

Gaga has publicly said that she has no issues with Madonna - and see's her as a role model. But for Gaga - it's a one sided street! :(
