Hayden Panettiere became a mum for the first time on Tuesday, according to her rep. The actress and her fiancé, Wladimir Klitschko, welcomed a baby girl, whom they named Kaya Klitschko. People reported she was 7 lbs., 14 oz. It's been an exciting journey for the new mum since news about her pregnancy was confirmed in June. Later that month, she debuted her baby bump in a one-piece swimsuit during a yacht day with Wladimir in Saint-Tropez. In August, Hayden's bump was front and centre as she and Wladimir soaked up the sun in Miami. At the eight-month mark in November, she rocked a bikini again while the couple vacationed in Hawaii. Congratulations, Hayden and Wladimir!
