Singer and Hollywood celebrity Ashlee Simpson was recently spotted going out for her usual Tuesday morning workout, the only difference this time is of course her growing baby bump. Simpson is indeed going through her pregnancy well as she still can do her usual work-out routine.

But worry not, Simpson reportedly does her cardio in a way that doesn't affect her pregnancy and in fact the work out reportedly helps her to be stronger by the time she delivers her baby girl. It has been revealed that the expectant mom-to-be does Cardio Barre with fellow fitness enthusiasts.

"Cardio Barre is a ballet inspired workout. Ashlee is a beautifully classical trained dancer. Hence her passion for Cardio Barre," Richard Giorla, founder and creator of Cardio Barre, told E! News recently. "The dance inspired ballet techniques are no impact/high energy so they are safe to do while pregnant," he added.

Simpson was spotted post work out looking hyped up with energy in her black leggings, matched with her black top and a pair of black sunglasses while making sure that she compliments her outfit with a blue jacket. It was surely a sweaty work out as the 'Pieces of Me' singer had her hair braided so that she can move well in her Cardio Barre workout routine. The singer and celebrity finished her look with a black long shoulder bag as well as a pair of workout shoes.

Good thing that the workout is safe as Simpson's family are quite excited to see yet another member of their growing family. "He's excited. He's so excited," Simpson previously told E! News, "He's excited that it's a girl, he thinks it's cute-the tea parties, she'll be adorable," she said of her first son Bronx, 6.

"He can't wait. He's going to be the big brother, be the boss. He's excited," Evan Ross added.
