Slim Sandra Bullock is accompanied by her stylish toddler Louis as she promotes new film in Europe

Sandra Bullock's little boy is quite the globe-trotter.
The star's whirlwind travel schedule seemed not faze her three-year-old at all as mother and son headed to the airport in Berlin on Wednesday.  
Sandra, who has been promoting her newest film The Heat, was seen leaving the Hotel de Rome in Germany's capital city with Louis nestled comfortably in her arms.

Louis was flight-ready in cuffed jeans, blue-striped hoodie and navy baseball cap, as well as white Adidas trainers.
The 48-year-old actress, who is of German descent on her mother's side, was casually attired in a beige jumper with belt and strappy flat sandals.
She wore her dark hair pulled back in a ponytail and wore dark sunglasses.

Unfazed: He may be only three, but Louis is already an expert traveller

Sandra had only just arrived in Berlin on Monday and on Tuesday attended the photo call to promote The Heat.
Last week the A-lister was glamorous in a sleek black gown to attend the London premiere of the action-packed comedy, which hits U.S. theatres June 28.  
Sandra plays uptight FBI Special Agent Sarah Ashburn who is forced to join forces with foul-mouthed Boston cop Shannon Mullins - played by Bridesmaid's Melissa McCarthy - to bring down a ruthless drug lord.

The stars got along swimmingly and the fact that they both have kids certainly helped.
Sandra adopted Louis as a newborn in January 2010 and Melissa has two children, Vivian, six, and Georgette, three, with husband Ben Falcone.
'Having kids connected us on a deeper level,' Sandra recently told Parade. 'And the things we’re obsessed with outside of being a mom are the same, too.'

Sandra told Collider.com: 'I would say it’s the rare happening when actors get together and you have chemistry, connection, just something that works, that’s bigger than what’s on the page. 
'And I think that we luckily had it, on an acting level and a comedic level.  
'Her style and my style are very different, but they always met in the middle and were absolutely appropriate for what was needed to happen on screen. 'Bridesmaids, cultural phenomenon now.
And while Sandra admits that all of their stunts were performed by professional stunt people, 'We did our own dancing.'
