Actress Sandra Bullock has revealed she spent the Mother's Day crying.
The 50-year-old actress admitted on "The Ellen DeGeneres Show" that she was feeling guilty of not giving birth to adopted son Louis.
"It was all happy tears. I just cry at anything now. I didn't (give birth to him), but I feel hormonally," she said.
The five-year-old started off the Mother's Day by singing a sweet serenade for her
"He sang me a song that he wrote... I didn't have the heart to tell him he plagiarized... (The song goes), 'There was a mom I love so much and Sandy was her name-o'," she added.
Bullock and Louis recently returned from his birth city of New Orleans.
