Reese Witherspoon

The ‘Legally Blonde’ star - who has Ava, 24, and Deacon, 20, with her first husband Ryan Phillipe, 49, and 11-year-old son Tennesse with her former spouse Jim Toth, 53 - would tell her younger self that only you can fix your own problems.

The 47-year-old actress said: "[I'd say] one is coming to save you and you will have to save yourself. And also that no relationship, no child, mother or father are going to fix your problems."
