Gwen Stefani reveals how hard it is to stay in shape
There’s no doubt about this… It’s Gwen Stefani‘s birthday.

The songstress — the lead vocalist for the rock band No Doubt — turns 43 on Oct.3. Stefani has transformed her looks since her years with the group, from total punk rocker to sleek and stylish mama.

She even traded in her bindi and crayon-colored hair for a platinum ‘do and signature red pout.

Stefani has also amped up her style with chic numbers such as draped one-shoulder frocks and silhouetted trenches.

What’s her style savior?

The wife of Bush musician Gavin Rossdale is probably in the best shape of her life — frequently flaunting her ripped six-pack and sculpted physique that she works hard to maintain.

Obviously everything fits like a glove on Stefani’s incredible bod’ — even cropped tops that she sports around Los Angeles, Calif.

Yet, the L.A.M.B. designer still glams it up for each occasion — accentuating her figure in elegant gowns as she rocks the red carpet for Tinseltown’s hottest bashes.

Stefani is also known for her minimalist style, but the “Hollaback Girl” doesn’t shy away from an exciting print when the right one comes her way.
