For those of you who question Lady Gaga'sÂ talent, you gotta see this video. LG belted out a farewell song last week to the daytime-talk legend that nearly brought Oprah to tears. It was a rousing performance that had the audience on their feet with a standing ovation. Plus, LG sits atop a high stool playing a high-heel piano (yep, you read that right!) that was designed by her 19 y/o sister. Apparently, talent runs high in the Gaga family!
