Beyoncé is already looking fit and fabulous after welcoming twins Rumi and Sir just a month ago, as she stepped out for a low-key event for the first time since giving birth on Thursday night.

 The new mom of three, 35, paired a corset-like mini skirt with a long-sleeved white top while with husband JAY-Z at an event celebrating Roc Nation artist Vic Mensa in L.A. – the same evening she dropped the first image of her twins on Instagram.

Beyoncé paired the entire look with sky-high block heels – which accentuated her famously toned gams – and a fur bag.
