No wonder Ali Larter has such awesome arms; she carries baby Teddy with her nearly everywhere she goes!

The Heroes star showed off her fit figure in skintight white pants and a causal black tee as she carted her sharply-dressed one-year-old to Whole Foods in LA, on Tuesday afternoon.

Larter has been hard at work filming scenes for the upcoming flick Lovesick with Friends star Matt LeBlanc, which centers on a man who goes clinically insane every time he falls in love, until he finds his perfect match.

Ali is also gearing up to return to the small screen in Fox's new spy drama The Asset, premiering this fall.

Her bikini body is definitely Heroes-worthy, but we hate to see Ali Larter sucking on a cancer stick -- yuck!

The hot momma of one showed off her perfectly toned body in a sexy white two-piece bikini, as she partied with friends in Malibu, California, on Saturday afternoon.

As the party went on, Larter covered up with a pretty sarong, and took to the dance floor to bust a move.

Put down those cigs, Ali!

While some A-list moms are still struggling to ditch the baby weight, Ali Larter looks like she's in the best shape of her life after giving birth to baby Theodore MacArthur!

The Heroes star showed off her perfect legs in sexy cut-off shorts while on an outing at Coldwater Park with her 17-month-old son, on Saturday afternoon, and there's no doubt she was the hottest mamma on the playground!

The 36-year-old mom of one is getting in as much time with her little man as possible, because she's gearing up start work on the upcoming Fox series The Asset, in which she'll play a globe-trotting human intelligence specialist!

That's quite a package you've got there, Ali!

The Varsity Blues star looked stunning in ripped jeans, a white blazer, turquoise heels and a sexy studded bag as picked up a huge box at the post office, and dropped it into the trunk of her Mercedes without any help!

After taking on butt-kicking roles in Heroes and Final Destination It's no wonder the hot mamma of one has the muscles to handle such a heavy task.

Larter is currently hard at work filming her latest TV show The Asset, in which she will play a super spy!

Ali Larter is one hip mom!

The Heroes actress, rockin' some black jeans and black converse sneakers, held on tight to adorable baby boy Theodore while running errands in Los Angeles. We have to admit, Ali's body is looking fab!

Larter, 35, will be starring in the upcoming Fox drama, The Asset. We can't wait to see her on the small screen again.

Looking chic in a loose-fitting sweater, skinny jeans and leopard-print ballet flats, hot mamma Ali Larter treated her darling son Teddy to a playdate on a sunny Wednesday afternoon, in Beverly Hills.

Little Teddy is probably the only one who can pull off wearing a Christmas sweater in January, and still manage to look adorable!

These days, the mommy-son duo is rarely seen apart, and that's just how Ali likes it. The star is currently taking time off from acting to be a full-time mom, but we have to admit, we really miss her on the big screen!

By far the hottest mamma on the playground, Ali Larter showed off her fit figure in a pair of skinny jeans, while treating 1-year-old son Theo to a fun-filled playdate at a park in LA's Coldwater Canyon, on Tuesday afternoon.

The former Hero's star seemed to bounce back into her post-baby 'bod shape almost overnight, but Larter admits working out has to fit in to her daily routine.

"From the morning through night, I just wear my workout clothes so that if I can grab
a half an hour here or there then I'm ready to go," she confessed at a Reebok event, adding "Being a new mom, my time is of the essence."
