Former England footballer Rio Ferdinand's wife Kate has opened up on being a step-mother and admitted that it's been a challenge. Kate, 28, last year tied the knot with the former Manchester United footballer, who lost his wife Rebecca to breast cancer in 2015.

She is a step-mum to three children—Lorenz, 13, Tate, 11, and Tia, eight. Kate broke down as she spoke on her relationship with the kids in a BBC documentary called Rio and Kate: Becoming a Stepfamily, adding, "It's hard for us so I just can't imagine how hard it is for the kids," Kate said. "I just want the children to be happy."
