Amber Rose Baby Bump Put on Show at MTV Video Music Awards 2012 (PHOTO)

Amber Rose put her baby bump on display at the MTV Video Music Awards earlier this week, in what is becoming a trend among celebrities.

Last year Beyonce delighted fans and VMA attendees by showing off her baby bump and making her official announcement that she was expecting. At that time Beyonce stood on stage and rubbed her belly giving a clear message that rapper Jay-Z and her were expecting their first child.

However, on Thursday night Amber Rose also chose to show off her baby bump. Fiance Wiz Khalifa told MTV's red carpet reporter Sway, "We had to do it with the whole world and just let everybody know we're expecting a beautiful baby, me and Amber."

The model, although of course delighted to be expecting, was not quite as high in the clouds as her fiance, telling Sway, "I'm hot and my feet hurt, I want to go sit down."

Previously it was reported that the couple had not planned the pregnancy in advance, but were delighted by the news nonetheless. It has also been rumored that the engaged couple may move forward their wedding plans in light of the baby news to ensure they tie the knot before the baby's arrival.

"Amber's already had to make some big lifestyle changes, like not smoking cigarettes anymore," a source close to the model has said, according to The Daily Mail. "As a model she's used to have a thin waist, so this is going to me an adjustment for her."

The couple announced their engagement on Twitter earlier this year: "She Said Yes," posted the rapper, who is also known as Cameron Jibril Thomaz.

He attached a photo of a diamond ring on Amber Rose's hand as evidence of their exciting news.
