Exclusive: Grace VanderWaal Pens Tearjerking 'Letter to Mom' for JJJ's Mother's Day Series

Grace VanderWaal won our hearts with one song, while her mom stood in the wings clapping and cheering her heart out.

The singer-songwriter shot to fame after her self-written song “I Don’t Know My Name” blew the judges away on America’s Got Talent.

Still, Grace might be the first to tell you, she still has a normal life. After all, she wasn’t allowed to get Snapchat until her 13th birthday earlier this year.

Here career is taking off so fast, and someone who’s at her side the entire way — for support and to keep her grounded — is Tina Vanderwaal.

For our multi-part Mother’s Day series, Grace really wanted to tell her mom how much she cares.

Dear Mom,

You have been there supporting me since day one and showing unconditional love. You can just hang out with me and watch Netflix, but also guide me through life’s challenges and womanhood.

The words I’m typing can’t say what’s really in my heart and the best I can explain it is that I love you. So much.

You are so hard working and even though I know we fight sometimes, I know you want the best for me. You deserve a day like Mother’s Day to celebrate and acknowledge what you do every day for this whole family.

I love you Mom.
