Watch the touching moment and listen to Swift open up about her recent struggles.

Taylor Swift Sings

Swift reminds us amidst the glitz and glamour that she’s human, too.

Normally, Taylor Swift’s shows make headlines because of the A-list guests she brings on stage, but Monday night’s show in Glendale, AZ highlighted another special guest: Maya Thompson.

Swift brought the crowd to tears as she opened up about her story knowing Thompson and her son Ronan, who passed away from cancer in 2011 at the age of three. Swift penned a song in his honor titled “Ronan,” made up of lyrics from blog posts written by Thompson, and performed it once during her appearance for Stand Up to Cancer several years ago. The 25-year-old sang it once more during her Glendale show after detailing her recent struggle with cancer – Taylor’s mom was diagnosed with cancer this year.

She said, “I think that in my opinion, one of the greatest things that a human being can ever do, is to go through something unbearable and then share their experience with the world. And I think, the braver you are, the more completely honest you are,” Swift told the audience, reports E! News. “There’s a woman here tonight named Maya Thompson…and I wouldn’t know half as much as I know about childhood cancer and childhood cancer research if she hadn’t shared her story about her son Ronan….The thing about childhood cancer is that it’s really really hard to talk about. And it’s really not something that you bring up…but the fact that she brought it up, she had this blog called Rockstar Ronan and I would read it every night. And in it was this account of what it was like to watch cancer take over my life. And since then, I’ve had cancer hit really close to me in my family. So because Maya’s right there, I would like you to give her a round of applause, please.”

Thompson took to social media after the show expressing her gratitude towards Swift. “I still can’t believe tonight. I still can’t believe you did this. This will forever be one of the most special moments of my life. Thank you @taylorswift for your beautiful heart and for never forgetting my Ro. I love you to the moon and back. #ronan #fuccancer #secretsong #1989 #allhailqueentaylor #myhero #swiftieforlife #rockstarronan @ronanfoundation,” she captioned an Instagram video from the concert.

It’s easy to get on Swift’s case over music distribution or drama with Nicki Minaj, but moments like this remind us why Swift remains one of the most sincere in music.
