While some women feel uncomfortable with the way they look during their last trimester of pregnancy, Victoria's Secret Angel Alessandra Ambrosio shows that she feels sexier than ever as she stripped down to her bare skin for a photo campaign for Vivara jewelry while 8 months pregnant. Check out the hot shoot, next!

Oozing confidence, eight months pregnant model Alessandra Ambrosio shows off her baby bump in a nude photo session for a new ad campaign for Brazilian jewelry brand Vivara and it seems like the Victoria's Secret Angel has every reason to be proud of her physique as she looks stunning. Flaunting her baby bump proudly, the mother-to-be for the second time, proves that pregnancy can too be sexy, which is not what most expectant mothers would say especially one month prior to giving birth.

The 31 year old model looks amazing in the new ad campaign for Vivara which shows bare images of the heavily-pregnant Brazilian bombshell, captured by the camera lens of acclaimed photographers Mert Alas and Marcus Piggott. In the campaign, Alessandra can be seen wearing the company's jewelry and nothing else, while posing in front of a window, surrounded by a sheer curtain which caresses her perfect looking skin. The photograph, which Ms. Ambrosio shared via Facebook, reveals a high dose of confidence that is exuded by the expecting mother, and apparently that is the power that pregnancy has over Alessandra as she revealed in an interview regarding the campaign that:

'A nude photoshoot was good, because pregnancy makes me much more confident. I'm proud of my body to be generating a life... I wasn't ashamed to do a nude shoot for two of my favorite photographers. I'm happy to have one of the most important moments of my life recorded by them.”

Apparently, the photo session took place behind closed doors, with only the photographers in the room, which enables Alessandra to have her share of privacy. While she has just recently entered maternity leave, she is determined to return to work in time for the opening of the Victoria’s Secret store in London, in July 2012, as she recently said that:

“I already have jobs planned for afterwards so hopefully will be back in shape. I told my booker and my manager; 'I know I have a job to do, so just book the jobs and hopefully it’ll be fine'.”

Ms. Ambrosio, who was already pregnant during the 2012 Victoria's Secret Show has revealed to her fans that this time around she and her fiance Jamie Muzar, whith whom she has a 3 year old daughter Anja, will be welcoming a baby boy. She wrote via Facebook that:

“We really tried to keep it a surprise but we were too anxious! Soon, we will have a little boy to rock our world!!”
