Leaving son Louis
with a babysitter, Sandra Bullock
made the most of a night out with friends Wednesday in London – looking smashing in a sexy black Monique Lhuillier dress and red heels.
The Oscar winner, 48, was spotted leaving the Nobu restaurant and heading to the Claridge's hotel in Mayfair.
She's currently in Europe to promote her upcoming crime comedy The Heat
, costarring Melissa McCarthy, with whom Bullock has become close.
"Having kids connected us on a deeper level," Bullock told Parade
recently. "And the things we’re obsessed with outside of being a mom are the same, too."
