Through son Ludwig (4), Cathy (34) and Mats Hummels remain connected - at least as friends - even after their separation. The three of them celebrated the football star's 34th birthday with a breakfast together. In addition to congratulations, the presenter cannot resist a small dig at her ex-partner.
