Taylor Swifthas a new best friend,Majesty Williams, and Swifties are raising funds for the lovable 7-year-old as well as other children theEras Toursinger met during a recent hospital visit in Florida. Swift visitedJoe DiMaggio Children's Hospitalon June 13, going room-by-room to speak with patients and staff. In a video postedto TikTok, Majesty combs her fingers through Swift's hair. Swift says, "You're so so sweet. She's my best friend." "I like Taylor," the 7-year-old says as she wraps her arms around the singer-songwriter and nestles her head onto Swift's shoulder. " She touched her hair to make sure Taylor was real," her mom, Shaneka Holloman, tells the USA TODAY Network. Majesty was born with hypertrophic cardiomyopathy, a condition where the heart muscle becomes abnormally thick and can block blood flow. At age 2, Majesty underwent a heart transplant. "I don't know whose heart she has, but whoever it was, was full of love, because my baby girl is full of love," her mom says. "She is strong. Three days after the transplant, she was walking down the hallway." On June 12, Holloman received a phone call from the hospital inviting her and her daughter to a function. "They said it was a surprise, but they didn't say what," Holloman says. "They told me to make sure Majesty looks cute. I thought it was going to be a therapy dog." That night, Swift and boyfriendTravis Kelcewent to Amerant Bank Arena forGame 4 of the Stanley Cup Finals. The following morning Holloman pulled out Majesty's denim dress in their Deerfield Beach, Florida, home. She combed her daughter's hair back in a high ponytail and clasped her golden "M" necklace. Then the mom and daughter drove to the Hollywood, Florida, building. At the hospital, Holloman — with her back to the door — watched her daughter mash Play-Doh. "Then I hear my baby say, 'Taylor Swift,'" Holloman says. "I didn't know what to say. I didn't know what to do. This is Taylor Swift, America's sweetheart." The singer and the girl talked for 15 minutes. Like any best friend would, Majesty asked for Swift's phone number. "She's been asking me if we got it, and I told her Taylor may call us one day," Holloman says. Swifties posted photos and videos of the hospital interactions on social media. Some influencers started fundraisers while others sharedGoFundMe pageslike Majesty's. She will have a heart condition her entire life. Fans raisedmore than $11,000. One of the other rooms Swift visited belonged to 2-year-oldAaliyah. The author autographed anEras Tour bookfor the little girl who had a brain tumor removed in September. The book appeared on Mercari marketplace selling for $500, and Swifties swooped in. One fan purchased the book and told the Mortensen family to keep it. AGoFundMe was set upwith a goal of $100,000. The fandom shared the page and donated $13 increments as a nod to Swift's favorite number raising more than $51,000. "Having to pay for medical bills, traveling, food, rent, and utilities while still trying to make my baby girl feel at home away from home, things have been difficult," mom Crystal Mortensen wrote on the post. "Anything will be greatly appreciated. The journey has just begun and will be a tough one, but my warrior princess got this. She's so strong. She's a fighter." A third patient,Zoe,has been battling neuroblastoma for almost seven years. According to theGoFundMethat's amassed $18,000+, the brave 10-year-old girl "has faced countless treatments, hospital visits, surgeries and medical challenges with incredible strength. Her journey has been long and difficult, but she continues to inspire everyone around her with her courage and positive spirit." The $100,000 goal would help the family with the financial burden of ongoing treatments.
