She has been keeping a low profile since welcoming daughter Rose Dorothy in 2014 with French husband Romain Dauriac.

But on Sunday Scarlett Johansson made sure to stand out in the star-studded crowd as she wore a red mini dress to the premiere of her new animated movie Sing at the Toronto International Film Festival.

Also at the event were the 31-year-old actress’ cast mates Reese Witherspoon, Jennifer Hudson, Tori Kelly and Matthew McConaughey, who brought his wife Camila Alves.

The blonde actress looked confident as she walked the carpet.

With her tresses blowing back, she flashed a megawatt smile at the hundreds of fans waiting outside.

The Lucy star’s dress moved nicely thanks to ultra light sheer fabric that gave a look at her sculpted arms. A nice bow tie in the front kept the number looking classy and conservative.

Scarlett has called the City Of Lights her home base since settling down with Dauriac.
