The Madonna and Lady Gaga rivalry is unlikely to end anytime soon.

Madonna recently added fuel to the fire. A video of her concert rehearsal in Tel Aviv was put on Youtube showing her singing “Express Yourself”, she then seamlessly transitions into “Born This Way” from Lady Gaga, finally finishing with “She’s Not Me”.  Tricky, Madonna, very tricky.

Watch the footage:

The feud between the two is based mostly on Lady Gaga’s song “Born This Way”. When it was first released its similarities to “Express Yourself” didn’t go unnoticed.  

Gaga famously told NiME, “What a completely ridiculous thing to even question me about… If you put the songs next to each other, side by side, the only similarities are the chord progression. It's the same one that's been in disco music for the last 50 years. Just because I'm the first f***ing artist in 25 years to think of putting it on Top 40 radio, it doesn't mean I'm a plagiarist, it means that I'm f***ing smart. Sorry."
