Sandra Bullock says she's happy to be single

Oscar-winner Sandra Bullock, who endured a highly public divorce from philandering husband Jesse James in 2010, says she is open to a new relationship, although she's perfectly happy as a single mother.

"If it should come along, great," she told Entertainment Weekly in its new issue, which named the "Gravity" and "The Heat" star its Entertainer of the Year. "But I feel like I'm not missing anything yet. Maybe one day I will. But my son [Louis] is 3 years old, which is an amazing age. Four is an even better age. So if something happens, great, but if not, I've got plenty to do."

Bullock, 49, who won the Academy Award for 2009's "The Blind Side," also put her contentment into a larger perspective, saying, "When people are like, 'Life is so good,' I go, 'No. Life is a series of disastrous moments, painful moments, unexpected moments, and things that will break your heart. And in between those moments, that's when you savor, savor, savor.' "

She said she hoped her film projects in the near future would allow her "to still be a stay-at-home mom. I have a feeling that work is going to shift now because I don't want to drag Louis around to places."

Ultimately, she said, "I'm so lucky with what I have and I'm so in love with our life and our routine and how simple and how massive it is. But whatever comes along."
