Get Demi's Flat Tummy
Hollywood fitness tips for enviable abs.
It’s high time to hit the gym if you wanna pull off this summer trend. From the runway to the red carpet, celebs and models alike have been showing off their stomachs in bare-midriff ensembles.

Some of the styles are more subtle than others, but one thing is for certain, these gals are fab-ab-ulous! Most recently, Jessica Biel sported the tummy trend when she stepped onstage for the Total Recall panel at the 2011 Comic-Con conference. 

The trend also transcends from the red carpet to weekend wear. Jennifer Lopez showed off her stomach in a more casual getup when she stopped off at Extra for their show at The Grove in Los Angeles. Meanwhile, fashion-forward celeb Nicole Richie bared a little midriff in a formal Halston gown for Elton John‘s Oscar party.
