Back in black: Beyoncé, 40, looked glamorous in an black off-the-shoulder dress that hugged her curves at the premiere of The Harder They Fall for opening night of the BFI London Film Festival

Beyoncé flaunted her figure in the skin-tight dress, which emphasized her hourglass figure.

The outfit featured a plunging neckline that highlighted her cleavage in a check-mark shape, with one side rising higher than the other.

The Crazy In Love singer’s black velvet dress nearly reached to the ground, but her black open-toe platform heels inched out just a bit.

Although she had a minimal presence on the red carpet, keeping the spotlight on the actors and crew, she put on a far more elegant display in a round room with mirror panels that made it look as if she was in a house of mirrors.

Although she showed off plenty of seductive looks, the singer–songwriter also gave off a rare smile.

Although she seems to have kept to herself for part of the evening to let the filmmakers shine, Beyoncé looked totally loved up with her husband Jay-Z in a car after the premiere.

She cozied up next him and wrapped her hands around his as he rested it on her leg.

The 99 Problems rapper looked debonair in a Tom Ford black tuxedo with a large bow tie.

He had his hair swept back in thick, short dreads and sported a rare goatee.

The couple have been together since after they collaborated on his track ’03 Bonnie & Clyde in 2002.

They quietly married in 2008, and Beyoncé gave birth to their first child, Blue Ivy, in January of 2012.

In June 2017, she welcomed a set of twins, Rumi and Sir Cater, though Beyoncé didn’t share news of their birth until a month later.
