Jennifer Garner is receiving plenty of praise for a performance not seen on television or the big screen, but on Instagram.

Videos by Rare

The actress posted a video of herself Thursday laughing and talking with slurred speech after a dental appointment while emotionally praising a song from the musical “Hamilton.” In the caption she wrote, “Throwback Thursday– that time I had dental anesthesia…laughing gas + novocaine + Hamilton = you’re welcome. ”

The video shows Garner riding in a car and telling someone on the phone how she couldn’t stop crying during a song in Hamilton because it was “so beautiful.”
