Taylor Swift‘s epic squad is helping her ring in her 26th year.

The pop star, who celebrated her birthday on Sunday, received a smattering of love on social media from her enviable group of friends.

Longtime bestie Selena Gomez shared a split image, which included a black-and-white photo of she and Swift in their younger days and a picture from Gomez’s recent appearance on the star’s 1989 World Tour, on Sunday.

“I don’t know life without you Taylor,” Gomez wrote on Instagram. “Happy birthday!”

Gigi Hadid, another one of Swift’s A-list friends, also used Instagram to celebrate the singer’s big day.

“What a year, T,” Hadid wrote alongside a gif of the pair hugging at this year’s Video Music Awards. “Love you, so proud and grateful to call you my friend. You are beyond. Happy Birthday – can’t wait to celebrate soooon.”

Jaime King, whose son Leo is Swift’s godson, posted an emotional message on the photo sharing site the day before the star’s birthday.

In the note, which she shared with a solo shot of Swift, King said that with the star’s music she grabs “the hearts of countless” people.

She continued, “As my sister, with your irresistible enthusiasm, un-f—— unbeatable passion and true honesty, feels like home. To have changed the perception of female friendships (even in the smallest way) because somehow, in this crazy world where women want to hurt each other, we have a thoughtful group of friends where we have chosen to love each other through it all, and support our peers along the way & with open arms you bring this sisterhood to life Intimately and sincerely, I love you, I am profoundly proud of you, your Light is a rare and brilliant gift.”

Swift, herself, documented the big day on social media with an old photo from her youth.

In the sweet picture, a younger (and adorable) Swift appeared excited.

“Today I begin my 26th year of freaking out over stuff,” she tweeted, poking fun at her famous surprised face.

The actress also announced that she had a “surprise” for her fans in honor of her 26th year. Swift will release The 1989 World Tour LIVE film exclusively on Apple music on Dec. 20.
