Even though their lives are crazy, Blair Waldorf and Serena Van Der Woodsen stick together through thick and thin while battling the gossiping Upper East Side of Manhattan.

Through a whole six seasons of “Gossip Girl”, B and S proved how to be the ultimate bestie while showing strength, honesty, authenticity and love.

Whether we need someone to adventure with to Central Park, shop for hours on Fifth Ave or simply need a shoulder to cry on, we could all use a B & S relationship and here are the 10 reasons why.

1. They have each other's backs no matter what.

2. They are always happy for one another.

Even if she doesn't want to show it, Blair is proud of Serena through all her ups and her downs.

3. They always keep each other up to date on their life, even when its pretty awful.

4. They never let each other settle for less than what is deserved.
