To kick off the first night of TODAY’s Making Space Wellness Weekend with Hoda Kotb, Rachel Platten performed for an intimate crowd—and ended the evening with a sweet surprise.

As she sang her famous “Fight Song” and was about to finish the final chorus, she called Hoda and several of the other retreat speakers to join her on stage, including TODAY special contributor Maria Shriver and co -It Cosmetics founder, Jamie. Kern Lima. You can Watch the special moment here.

The women gathered around Platten’s piano for the emotional moment as the crowd joined them for the final chorus and Hoda clapped. For a few brief moments, the group even went a cappella, led by Platten drumming on the piano.

“Someone had whispered to me right before we went on that Hoda wanted to sing,” Platten told TODAY.com when asked about her inspiration for the moment.

“I said, ‘Her do what?’ I love her. I like that about her. She is the best. I also got to see her… face and this is her event, I thought she deserved to be on stage during her favorite song right now,” Platten recalls.

“Her joy is so contagious. I thought it would be like a triple dose of the energy I was already feeling.”

TODAY’s Making Space Wellness Weekd with Hoda Kotbsponsored by Miraval Resorts & Spas, features speakers like Platten as well as experts in happiness, breathing, neuroscience and a host of other topics. About 150 guests gathered in Austin, Texas from across the country to hear from Hoda, who opened up about her own health journey, the experts and each other.

Before the show, Platten and Hoda had a candid conversation about some of the singer’s mental health issues, including a struggle with postpartum depression after the birth of both daughters, now 3 and 5.

“When I turned 40, I feel like everything fell apart,” Platten told Hoda. “Everything kind of fell apart… the ability to keep up the charade of being so nice all the time and all of a sudden this angry version of me was here and I was like, who is she? I don’t like her. But she was there and she was always there… and I got to know her.”

“Something I’m working on in my life (is) just learning all the different parts of me,” Platten continued. “There’s a part of me that’s very empowered and that wakes up excited… and then there’s parts of me that I’ve learned to know and not extend over the last seven years that aren’t quite all that, and that he didn’t want to be ignored after a lifetime.”

“Starting to learn all the different parts of me and loving them and loving myself fully was the most healing work I’ve done in my life,” added Platten. “I love who I am now, me, because of it.”

Platten tells TODAY.com that this new phase of her wellness journey involves listening to her body and prioritizing what it needs.

“I try to ask my body, ‘Hey, what are you doing today?’ Sometimes it’s heavy weights and sometimes it’s gentle yoga, but it’s just that break I take to put a hand on my heart and just check in,” she explains. “We didn’t do that before. I would train more to fit sample sizes or something, and now I train to be strong and carry my girls.”

She also incorporated some of her health practices, such as journaling, into her new album, “I’m Rachel Platten” which he released last month.

“I’m always looking, as a songwriter, for what’s the truest thing and what’s the cruelest thing I can say. I think that’s where the need is. That’s what I’m really interested in as a musician,” she says. “I’m extremely honest and extremely literal… Some of these are journal entries, literally from my hand, tear-stained pages in a song.”

When asked what drew her to participate in TODAY’s Making Space Wellness Weekend with Hoda Kotb, Platten explains, “I love the idea of ​​making space for ourselves. … It is very difficult to choose the time for yourself.”
