"Victoria is the first person I turn to. She has kids that have been through all the stages. She gets it, she does the juggle. She's there for me whenever I need advice. Eva told The Sun Online.
"We have play dates and the best thing is that Harper is a great babysitter. She adores my little Santi."
Victoria has sons Brooklyn, 20, Romeo, 17, and Cruz, 14, as well as daughter Harper, eight, with husband David.
