No doubt about it: Beyoncé knows how to work a baby bump!

Hitting MTV's Video Music Awards on Sunday night, the pop superstar glowed in an orange gown that revealed her burgeoning belly to the world.

But the Grammy winning-diva, 29, was just getting warmed up.

Taking the stage during the live show to perform her buoyant single "Love on Top," Knowles strutted out in black stiletto heels, a black pantsuit and a purple sequined jacket.

"Tonight I want you to feel the love that's growing inside of me!" she told the cheering crowd.

Once Knowles wrapped the performance, she unbuttoned her jacket and triumphantly rubbed her belly – while the cameras cut to beaming dad-to-be Jay-Z, who was getting wild congratulations from Kanye West.
