It seems as if the the experience of  pregnancy is going to Ashlee Simpson's head.

The mum-to-be found the best way to show her new fuller figure- wearing a dress so low cut her breast almost fell out.

And with a confident stride it looked as if the singer wanted to shout out her pregnancy from the roof top.

Proud parents to be: Ashlee and her husband Pete Wentz after they announced that she was pregnant

With a big smile on her face  the singer made no attempt to cover her steadily growing breast that were proudly on display as if they were saying 'out with the slim teenage Ashlee and in with the curvy voluptuous Mrs Wentz,'

Wearing a long brown dress and flip flops  the 23-year-old causally went about her business clearly ecstatic at her fully formed body.

Matching her copper hair, the dress fitted her body like a glove and clearly showed her growing baby bump but it was her cleavage that did all the talking.  

With no bra under her garment the soon to be mother could not resist but show her steadily well defined boobs.

Now in the fourth month of her pregnancy the proud sister of Jessica  glowed as she made her way out of Ren Mar studios.

This is the first child for the singer who recently married 28-year-old Fall Out Boy singer Pete Wentz.

Simpson announced that she was expecting a child soon after their wedding and the couple as said to be thrilled by the news.
