Taylor Swift, 34, delighted fans with a heartfelt comment on Selena Gomez’s, 32, Instagram post announcing her engagement to record producer Benny Blanco, 36. In the comments, Swift revealed that she would be the flower girl at the upcoming wedding. Her playful response quickly gained attention, amassing over 172,000 likes within just an hour.

Selena stunned her 422 million followers on Wednesday night when she shared the first photos of her stunning engagement ring, captioning it, “Forever begins now.” The announcement came after a year and a half of dating the producer.

Swift and Gomez’s friendship dates back more than 15 years. They first met in 2008 while both dating members of the Jonas Brothers — Taylor with Joe Jonas, and Selena with Nick Jonas. Over the years, their bond has only grown stronger, with Selena referring to Taylor as her “only friend in the industry.” In a 2017 KIIS FM UK interview, Gomez even mentioned that their friendship was the best thing that came out of their previous relationships.

Recently, however, Gomez was reportedly concerned about Swift’s relationship with NFL star Travis Kelce, 35. A source revealed that Gomez thought Swift was moving too quickly in her new romance, especially given the more public nature of the relationship. Despite this, the friendship between Taylor and Selena remains solid, with Taylor continuing to support her BFF on her exciting engagement milestone.

In response to the engagement, Selena’s fiancé Benny Blanco shared, “hey wait… that’s my wife.” Meanwhile, celebrity friends like Jennifer Aniston also congratulated the couple, with Aniston writing, “HONEY!! Congratulations sweet mama!”
