Hilary Duff's Santa Monica Shopping Trip with Luca

Showing off her sweet bundle of joy, Hilary Duff headed to Santa Monica, California with a gal pal for a day of shopping on Thursday (August 23).

Juggling a massive Louis Vuitton bag with one hand, and her son Luca with the other, the gorgeous new mom strutted behind a stroller in brown ankle boots, colorful skinny jeans and a black top.

Hilary's shopping outing comes the day after she shared a stunning close up of herself on Twitter adding the message, "Red lips coming out to play tonight;)."

Still working hard to shed the pounds she gained from pregnancy, Miss Duff kicked off her Thursday with a shadowboxing session in Hollywood, California wearing a camouflage top and black leggings.
