These days it might seem like celebrity relationships go sour faster than a carton of milk, but the ones that last are rare and special. For some celebrities, it took years of dating the wrong people to find their happily-ever-after. When they did, though, they were able to look back on past relationships and identify the reason why things went so bad, and how they could improve in the future.

While we are not naive enough to believe that all Hollywood romances are real-life fairy tales, that doesn’t mean that famous couples don’t have some valuable relationship advice to offer us mere mortals. Here are some amazing celebrities, some married and some single, that are sharing some insightful and totally achievable tips for a happy and strong relationship.

Beyoncé

Beyoncé and Jay Z are one of the most iconic couples of the current generation. They hold the top spot for good reason. They are a power couple that supports each other. However, Beyoncé still maintains her independence and encourages her fans to do the same in their relationships. In an interview with GQ, Beyoncé said, "I was independent before I met my husband, and we have such a natural chemistry and a genuine relationship, and it's based on the things that relationships are supposed to be based on. I've seen, growing up, when a woman or a man in a relationship—it doesn't matter which one—doesn't feel confident, they feel a bit trapped. Your self-worth is determined by you. You don't have to depend on someone telling you who you are.”

Ellen Degeneres

Talk show host Ellen Degeneres has been married to Portia de Rossi for over a decade. Ellen said the relationship has lasted because Portia is her "best friend". Ellen understands just how special that is and said she is grateful for Portia because not everyone finds that perfect balance of love and friendship. When Ellen and Portia got married, Portia said, "It’s good to be loved, it’s profound to be understood." Communication is the key to their solid relationship. Ellen also was quoted saying "Portia understand me...that is the best gift anyone could have ever given me." It is important to find someone that will not only listen to you but take the time to understand where you are coming from.

Jessica Biel

Actress Jessica Biel is married to superstar Justin Timberlake, but their star power does not negatively affect their relationship. In an interview with People, Biel said the secret to their happiness was “Communication, communication, communication.” She continued by saying “The ability to be really honest about how you’re feeling and what your needs are. Just be able to communicate really honestly with your partner. That’s worked for us so far. I would never want to speak on anyone else’s relationship, but that’s what we do.” Despite rumors of cheating and lying in their relationship, the couple has stood strong next to each other and kept their family together.

Kristen Bell 

Actress Kristen Bell has been married to star Dax Shepard since 2013. Recently, Bell took to Instagram to share her gratitude towards her marriage and offer advice to her newly wedded friends. In the post she wrote: "Vulnerability always begets connection and intimacy. Stay vulnerable with each other. in 10 years, when the dopamine has waned, remember: Life is a crazy ride. It’s a privilege to go through it with a partner. Take necessary separateness. It will make your marriage better. Loving someone despite their faults, failings or other character defects is the most powerful loving thing you can do. Rejoice in what makes the other person happy, and allow them their individual interests. Know that everyone is doing the best they can with what they’ve got. So get a bigger emotional toolbox to fix your problems."

Taylor Swift

Taylor Swift is known for her songs about the terrible relationships she has been through. But through all of the bad relationships, Swift has been in, she’s learned a bit about what makes a good significant other and what doesn’t. Over the years, she’s been open about the mistakes she made in relationships and said it is a normal part of life. Taylor gives advice to her fans regularly, but in an issue of “Seventeen”, she really emphasized loving yourself first and not chasing after a relationship. She wrote in the column, “Remember that people have to fall in love with you because they want to, not because you want them to. Don’t chance ruining your friendship by chasing him before he’s ready. You just have to wait for him to turn it into something more, if and when he wants to.”

Reese Witherspoon

Actress Reese Witherspoon has said that one of her top priorities is for her husband, Jim Toth, to be happy. In an interview with Glamour she said, "I want so much for him to be happy, and he wants me to be happy. That's a big part of my day, thinking, 'Is he happy?' And for him, 'Is she happy?'" By putting each other's happiness before their own, they build a love relationship that is built on serving each other. She also said in the interview that it is important for women to never stay with someone who holds them back. "Run away from a man who can't handle your ambition", Witherspoon advises.

Tina Fey

Superstar Tina Fey said the best advice she ever received for her marriage was from her mother-in-law. In an interview, Fey said, "The only thing that comes to mind is my mother-in-law, before I got married...'My only advice for marriage is don't fuss too much.' She's a little Southern lady, and it's so true. Sometimes if you're not really mad about it, don’t make yourself mad about it because you think you should be. Like, who cares?!" Fey takes that advice and tries to go with the flow in her marriage. Not taking life too seriously or putting too high expectations on your partner will help it last longer and stifle fights.

Even Hollywood’s biggest celebrities are not immune to relationship problems and struggles. Every union is bound to run into some difficult points, so it is important to learn the strategies that allow you to overcome them. These celebrities have given it their all in their relationships and are passing on great advice to their fans so that they do not have to learn the hard way.
