This was the 35-year-old's first public appearance after welcoming her son Sebastian six months ago.
She walked the red carpet in a sleek white jumpsuit by Osman and completed the look with pearl collective spike earrings, reports eonline.com.
When asked about the secret behind her perfect physique, she replied: "It's a lot of working out and a really good diet!"
She emphasised that she sticks to the old-fashioned way to lose weight - diet and exercise.
"Diet as in really healthy food. I wish there was a magic pill you could just pop in! But unfortunately, it's exercise - I've been doing Pilates, and cycling, and hiking. That's pretty much my routine, as often as possible," Akerman said.
"CBGB", a historical about the New York City punk-rock scene and the venerable nightclub - CBGB, also features actress Ashley Greene.
