London, April 21 (IANS) Pop star Lady Gaga was "shocked" by comparisons between her "Born This Way" and Madonna's 1989 single "Express Yourself".

"I was f***ing shell shocked by it. If you put the songs next to each other, side by side, the only similarities are the chord progression. It's the same one which has been in disco music for the last 50 years," contactmusic.com quoted her as saying.

"Just because I'm the first artist in 25 years to think of putting it on Top 40 radio doesn't mean I'm a plagiarist, it means I'm f***ing smart. Sorry," she said.

Gaga also feels the message of the song, which has been hailed as gay anthem, came to her from god, and people are always looking to criticise her just because she has become so famous.

"I feel like, honestly, that god sent me those lyrics and that melody. When you feel a message to give to the world and people are shooting arrows through it - there's no way for something that pure to be wrong," she said.
