The 'Sexxx Dreams' hitmaker visited the Louvre art gallery in Paris on January 20 and became emotional when she saw the portrait by Wilson, reported Contactmusic.
"I went to the Louvre today and saw the portraits Bob Wilson made of me. It was such a special moment," she posted on Twitter.
The 27-year-old singer looked particularly striking in the outfit she wore for the visit, which included a long silver braided wig, metallic chequered catsuit and huge black platform shoes.
Robert's exhibition at the Louvre is titled 'Living Rooms' and also features a fifty minute video of Gaga.
