There is no denying that Diana Ross‘ grandkids are her biggest fans. The iconic singer took the stage as she accepted her Lifetime Achievement Award at the American Music Awards and sang her biggest hits. However, it was her granddaughter Jagger who stole the spotlight when she was spotted singing along to “I’m Coming Out” in the front row.

Joined by her parents Evan Ross and Ashlee Simpson, the two-year-old girl knew all the words to her grandmom’s song — and it was seriously the cutest thing ever. Eventually, Jagger, along with her older brother Bronx, 9, and Diana’s other grandkids, including fellow scene stealer Raif, 8, joined the icon on stage, but she was visibly nervous. Watch the video below to see the touching moment.

Diana’s extended family was on hand to witness the 73-year-old beauty honored, and she made sure to thank them during her heartfelt acceptance speech. “This is all about love. This says it all, this is my family,” she said before her grandson took the mic and added, “Grandma, I love you, and I’m so proud of you.”

Her famous fans also took the time to open up about the influence Diana has had on the world. In a pre-taped video, Barack and Michelle Obama congratulated the former Supremes member before Taylor Swift sent her own sweet message.

“I don’t personally know anyone in music who hasn’t been inspired by you and influenced by you,” Taylor said. “You are elegant and fierce and strong and brave and you have paved the way for everyone who does what we do now, including me. So, thank you.”

Before the show, her son Evan also sent her some love on social media. “TODAY is the DAY. @amas @dianaross #amas. Can’t [wait] to celebrate MOM,” he wrote. Her daughter Tracee Ellis Ross hosted the show, making it the perfect night for the famous family.
