Over the years, we've come to love celebrity moms and the support they offer. Through our interview series, Four Questions About Motherhood, we've quickly learned the root of their wisdom — their mothers! Answering the question "what's the best trick your mama taught you?" every response is filled with genuine advice that is endearing, sweet, and often comical. In honor of Mother's Day, we've rounded up these celebs' best-kept secrets from stars like Jessica Alba and Debra Messing. We're loving the honesty, and so will you!
