Rita Wilson and Tom Hanks have been married for 37 years—a lifetime in Hollywood. When Wilson shares her relationship wisdom, it's worth listening. Her advice isn't about grand gestures but the unglamorous, everyday habits that build a lasting bond.

As Valentine's Day nears, we asked celebrities for the best relationship advice they actually use. The answers from stars like Olivia Culpo, Kelly Rowland, and Matthew McConaughey focused on respect, kindness, and small, consistent efforts.

Rita Wilson insists on sharing a bathroom: "You have to be able to talk when getting ready." Kelly Rowland emphasizes giving each other space to grow and asking simple questions daily. Scott Hoying of Pentatonix advises, "Date someone kind. You can get through anything with sweetness and respect."

Other insights include never going to bed angry (Duff McKagan), being each other's number one supporter (Mark Hoying), and finding laughter in tough times (Alyssa Milano). Olivia Culpo highlights her father's wisdom: "Respect is the foundation." The collective advice is refreshingly honest about the real work of love behind closed doors.
