'Bachelor' Alum Carly Waddell Wears Lady Gaga Shirt Onstage After Criticizing Her

Singer Carly Waddell — more known for her TV dating conquests — opened for Nick Carter Thursday wearing a t-shirt with Lady Gaga sitting at a piano. Interesting, since she had a huge issue with the star doing just that during their time together at college.

In fact … Carly said she would be driven crazy by the singer showing off her vocals on the piano when while they were in an NYU cafeteria — a statement that caused widespread fury among Gaga’s Little Monsters.
