Since we lost interest in Anne Cox, the woman who birthed Harry Styles, 54-year-old tennis coach Judy has emerged as Crush’s new favourite MoT (Mum on Twitter). What her Wimbledon champ of a son lacks in wit and charisma, Mrs M makes up for in spades, serving aces in the form of an RT followed by a put-down. Yoko Ono is her latest grudge match: ‘@yokoono: “This is a room suffocating with no empty space. Sit in it.” No thanks.’ Ha! She just says what we’re all thinking. Not even her own son is safe. When Murray tweeted a photo of himself at a party with a typically dull New Year message, his mum retweeted it with an ‘oh dear’. Judy is the kind of no-nonsense gal we’d call in a crisis. We want her on our side, shouting and fist-pumping us through a losing streak. If anything might inspire Crush to greatness, it’s Judy — the world's ballsiest sports mum.
