Amber Rose, Wiz Khalifa announce a VMA baby

What is it about a moon man that inspires fertility? For the second year in a row, a star couple has announced a pregnancy at the MTV Video Music Awards: This time it’s Amber Rose and rapper Wiz Khalifa expecting.

Beyoncé broke Twitter records for speed in sharing news of her bundle, now the well-dressed tot Blue Ivy Carter, when she showed off her baby bump at the 2011 show.

“We do know the sex, but we’re [keeping it private] for now,” Rose, rocking a healthy bump in an embroidered black dress, told People on Thursday.

“We just found out two days ago, so we’re super excited.”

The couple proudly displayed Rose’s belly on a carpet that saw traffic from Nicki Minaj, Katy Perry, Rihanna, Taylor Swift, Green Day, Drake and One Direction.

Wiz was only starstruck about the bun in Amber’s oven.

“I’m going to the best dad and the best performer and the best husband that I can be,” he added to the mag.

Amber and Wiz are engaged to be married. When the Ministry caught up with the model and Smirnoff spokeswoman in April, she kept mum on the date but mentioned she’d found the perfect dress.

That may need some altering.
