Taylor Swift Surprises Couple at Their Wedding, Sings ‘Blank Space’

She's the best wedding crasher ever! Taylor Swift surprised a couple at their wedding in New Jersey on Saturday, June 4, and even sang the groom's favorite song at the reception.

Max Singer is a huge fan of the "Bad Blood" songstress, and his sister wrote a letter to Swift back in April telling her how he had married his fiancée, Kenya Smith, at his sick mother's bedside.

Singer and his mom had even done a mother-son dance in her hospital room to "Blank Space," but she passed away before he could dance with her at Saturday's reception in North Beach Haven.

And so a plan was hatched.

Singer's sister was able to keep the secret, so the entire room was surprised when Swift, 26, showed up, wearing a stunning strapless gown, with her hair in an updo and red lips.

"Taylor Swift was awesome," guest Ashley Berg, the bride's sister, tells Us. "She congratulated them and gave them a wedding gift — a painting saying, 'So it's gonna be forever' with the date."
