Selena Gomez, who recently got married to Benny Blanco in a dreamy wedding, shared an unseen video featuring her best friend Taylor Swift cheering for the bride on her special day.

Selena took to Instagram to congratulate Taylor on her latest album, The Life of a Showgirl, alongside an unseen video and two photos of the best friend duo at former's wedding in Santa Barbara, Calif.

Along with the post, she wrote in the caption, "In honor of SHOWGIRL .. blessed to have you by my side almost 20 years later gator! I love you @taylorswift forever and always."

The video shows Gomez in her getting-ready suite, dressed in a white slip dress and veil, with Swift sitting beside her in a sparkly floral gown and her signature red lipstick. “Are you even serious?” Swift asks while holding her phone and zooming in on Gomez, who laughs. “What? Look at her. Oh my God! Oh my God!” she exclaims. Gomez responds, “I’m so happy. I’m getting married. Finally!”

The photos give fans a behind-the-scenes glimpse of Selena and Taylor together. Selena also included a screenshot of one of Taylor’s songs, “The Fate of Ophelia,” from her new album.
