Low key and make-up free: Sandra Bullock sports casual gym gear as she collects three-year-old son Louis from school

Her name has recently been touted as a strong possibility to be in line for another Oscar nomination next year for her role in space film Gravity.

But Sandra Bullock looked like just another everyday mother as she picked up her son Louis from school in Studio City, California on Tuesday.

The 49-year-old had obviously just come from a workout session at the gym as she was still wearing cropped stretch leggings and a grey zip-up sweatshirt over a bright blue T-shirt.

That's my boy: Sandra Bullock picked up her little lad Louis, who will be four in January, from school in Sherman Oaks, California, on Tuesday

Her thick brunette hair was pulled back off her face and her eyes were hidden under a large pair of sunglasses.

The Gravity star was carrying a green hoodie which probably belonged to her adopted son, who will be four in January.

The little lad ran in front of his mother, looking adorable in tiny denim jeans and a dark grey Beatles' Hard Day's Night T-shirt with light grey arms as he carried his school lunch pack.

Sandra stopped to chat with some of the faculty members outside in the parking lot before driving away.

Juggling act: Sandra balances her hugely successful film career with motherhood

The star admits that Louis is the main man in her life, after her painful 2011 divorce from Jesse James. The Monster Garage host admitted to infidelities which ended their five-year marriage.

She recently told Entertainment Weekly that she doesn't feel the need to hit the dating circuit because she and Louis are having so much fun.

'My son is three years old, which is an amazing age,' she stated. 'Four is an even better age. So if something happens, great, but if not, I've got plenty to do.'

Cuddling up: He may be small but Louis, seen her in March, rules the Bullock household

But the Virginia native would be open to expanding her family if the toddler is happy to share his home with siblings.

She told the Daily Mirror newspaper: 'If all of a sudden my house had eight kids in it, if it was OK with Louis and it felt like a good safe family, I would be fine with that.

'It would be because that is what my home is for. So it is up to him. He is the boss of the house so I have to abide by his rules.'
