Sandra Bullock's son Louis is Santa's little helper as they celebrate first Christmas together

Sandra Bullock's son Louis is Santa's little helper as they celebrate first Christmas together - It has been a year of incredible highs and lows for Sandra Bullock, but the actress is ending it on a very joyful note as she prepares to celebrate her first Christmas with baby Louis.

The 46-year-old actress and her son were seen getting into the festive spirit as they attended a party in Santa Monica yesterday.

She doted over the 11-month-old as she chatted with friends and at one point placed a Santa hat on his head.

Louis also took a pony ride under the watch of other guests, although he looked a little apprehensive as he sat in the saddle.

He seemed much more comfortable on his mother's hip and the pair eventually headed home after a long day of fun.

Sandra, this year won her first Oscar for The Blind Side and also endured the breakup of her marriage to Jesse James, says her son is now her full focus.

'Louis's got the stage,' she said recently of her son, who she secretly adopted in January.

'No one understands the shift in priorities about having a child in your life that you are responsible for, until you have a child in your life.

'It naturally shifts. It just shifted the first day I met him. It was like he'd been there the whole time, yet everything was different.'

There are rumours Sandra will reunite with Jesse over the holidays to celebrate Christmas together in Austin.

Sandra became very close to his three children Sunny, 7, Jesse Jr., 13, and Chandler, 16, during their marriage and wants Jesse to be involved in Louis' life.

'Sandra wants to make sure Louis grows up knowing Jesse’s children,' an insider told In Touch Weekly magazine, 'so she is willing to put the past behind her for the sake of the kids.'
