Sandra Bullock & Louis: Bundled Up in the Big Apple!

Sandra Bullock carries her adorable son Louis while running some errands on Thursday (January 6) in New York City.

The 46-year-old actress recently rang in 2011 with pal and The Proposal co-star Ryan Reynolds at her restaurant Bess Bistro in Texas.

But rumors that there may be a romance starting are “ridiculous,” a source told People.

“They have been friends for 10 years and they celebrated New Year’s with others. That’s it. They really are just friends,” added the source.
