The tears streaming down the cheeks of a baby girl provide the perfect indication of how touched she was by her mom's singing in a video that went viral on YouTube Tuesday.
In the video, which was headed toward 5 million views, 10-month-old Mary-Lynne Leroux reacts to her mother, Amanda, singing the song "My Heart Can't Tell You No." The 1988 Rod Stewart song was covered by country singer Sara Evans on her 2011 album "Stronger."
The family lives in Ontario, Canada, according to a story on rightthisminute.com.
Little Mary-Lynne smiles when her mom first starts singing. But with the camera, operated by her dad, Alain, focused on her face, it's clear that the girl's eyes are filling with tears, and then her face starts to crinkle. She raises her eyebrows and smiles again before looking like she's about to start crying. A tear runs down her cheek.
"That's my granddaughter. It breaks my heart every time I look at her," reads a comment on the video from Herve Leroux. "She will probably be an actress one day. LOVE her to pieces. xxoo."
More than a minute in, mom keeps singing as Mary-Lynne is clearly gripped with emotion. With a hard blink of the eyes, more tears come and the baby girl whimpers.
"Awww, you feel the pain in the song, yeah honey?" Amanda says after she stops singing. "Mommy's done."
And with that, the little girl lets out a laugh.
