Taylor Swift attended the Met Gala on Monday in New York City, but it wasn’t boyfriend Calvin Harris she had on her arm. Instead, T-Swift attended with bestie Selena Gomez.

“It’s going to be the best,” Gomez told Access Hollywood last week. “It’s kinda like prom for fashion.”

This isn’t the first time the BFFs attended an event together. In fact, the two walked hand in hand at this year’s Grammy Awards, giving us all major BFF goals.

Both of us have kind of stuck it out and hung in there through all the different changes we’ve gone through,” Swift said in an interview with E! News. “Longevity is something you really can find very precious and rare in friendships.”

The love from Gomez is certainly mutual.

She supports me and never judges me,” said the “Hands to Myself” singer about her bestie when appearing on The Talk back in 2014. “She thinks I should constantly surround myself with people who are going to make me better, that are going to challenge and motivate me.'”
