The pair married in 2010 and eventually divorced in 2015 citing irreconcilable differences. They both requested primary physical and legal joint custody of their son. https://www.instagram.com/p/BiyCCYwnh7N/?hl=en&taken-by=hilaryduff Hilary began dating her current boyfriend a year and a half ago. Earlier this week, she told E! News that she was really happy in the relationship. She said: "I got a really nice guy. He's so great." Lovely. She also said that her mum met Matthew over the weekend at his birthday. She said: "... and she was like, 'I just love him. I love him so much. He's the best.' I'm like, 'I'm here. I exist, you know? You're always on my side!' She's such a traitor."
