Sandra Bullock through the years:

Bullock, 51, has previously been linked to actor Chris Evans, 34, after her split with ex-husband Jesse James in 2010 due to infidelity news.

Despite much buzz about her dating life, America's Sweetheart has been in full-on mommy mode with 5-year-old Louis. She recently dished to Ellen about a tender moment she shared with her son on Mother's Day this year.

In the tune of "Bingo," Louis sang: "There was a mom I love so much and Sandy was her name-o."

"And then he played the harmonica in between and then he just kept looking at me. And I just, ya know ... " she said as she pointed to her tears.
