While Kinney appeared to be in high spirits with his co-stars, he hasn't addressed his split from the "Born This Way" singer.
Lady Gaga broke her silence on the breakup with an emotional Instagram on Tuesday, where she asked for fans to please "root them on."
"Taylor and I have always believed we are soulmates," she wrote. "Just like all couples we have ups and downs, and we have been taking a break."
"We are both ambitious artists, hoping to work through long-distance and complicated schedules to continue the simple love we have always shared," she continued. "Please root us on. We're just like everybody else and we really love each other."
