Lady Gaga is not a stranger to a wild show - having put on unforgettable performances on her five concert tours. However, on Sunday she posted a snap from a show that she believed would resonate in her memory - her performance with Tony Bennett at the New Orleans Jazz & Heritage Festival. 
The 29 years old star modeled a trio of eye-catching outfits as she took to Gentilly Stage, and shared a glimpse at the night on Instagram, captioned: 'Tonight I will never forget.'
