Please answer a question about the following article about Josip Broz Tito:

His best known wife was Jovanka Broz. Tito was just shy of his 59th birthday, while she was 27, when they finally married in April 1952, with state security chief Aleksandar Ranković as the best man. Their eventual marriage came about somewhat unexpectedly since Tito actually rejected her some years earlier when his confidante Ivan Krajacic brought her in originally. At that time, she was in her early 20s and Tito, objecting to her energetic personality, opted for the more mature opera singer Zinka Kunc instead. Not one to be discouraged easily, Jovanka continued working at Beli Dvor, where she managed the staff and eventually got another chance after Tito's strange relationship with Zinka failed. Since Jovanka was the only female companion he married while in power, she also went down in history as Yugoslavia's first lady. Their relationship was not a happy one, however. It had gone through many, often public, ups and downs with episodes of infidelities and even allegations of preparation for a coup d'état by the latter pair. Certain unofficial reports suggest Tito and Jovanka even formally divorced in the late 1970s, shortly before his death. However, during Tito's funeral she was officially present as his wife, and later claimed rights for inheritance. The couple did not have any children.

How old was Jovanka Broz when she married Tito?
27
