Los Angeles: Singer Taylor Swift's friend and country music star Kelsea Ballerini believes the "Blank space" hitmaker is "fine", despite her recent split from Scottish DJ Calvin Harris. Ballerini is confident she will be alright because she is such a "strong" person, reports etonline.com. "She is incredible. She is a strong chick, I'm sure she's fine," Ballerini said at the CMT Music Awards on Wednesday. However, the 22-year-old singer admitted she was sad the couple had called it a day. "It's a bummer," she said.
