Sandra Bullock celebrated Mother’s Day with a lot of tears. The actress tells Ellen DeGeneres that her son, Louis, revamped the lyrics to ‘Bingo’ in honor of his mama.

“He sang me a song that he wrote,” says Sandra. “He said ‘I wrote you a song,’ and I didn’t have the heart to tell him he plagiarized. But it was, you know, ‘Bingo.’ You know ‘Bingo,’ the song.”

Louis replaced the word, ‘Bingo’ with ‘Sandy,’ and referred to his mom as someone he loves dearly. “He played the harmonica in between and then he just kept looking at me,” says Sandra. The star tells Ellen that she was in tears by the end of the presentation.

“It was all happy tears,” shares the star of her entire Mother’s Day experience. “Everything he does [makes me cry].”

Louis will celebrate his sixth birthday later this year. He is Sandra Bullock’s only child. Watch the star dote on her son below!
