Her birthday boy! Doting mother Alessandra Ambrosio is fit in neon as she carries little Noah on her hip

He turned one year old on Tuesday.

And despite his growing frame Alessandra Ambrosio is determined to keep her son Noah Mazur close.
The
Victoria’s Secret model, 32, showed exactly why she is so lean as she
carried the little boy around Santa Monica, California.

Running errands: Alessandra Ambrosio took little Noah out in Santa Monica, California on Wednesday

Alessandra was hard to miss as she sported a neon green crochet top over a red vest and rolled up blue jeans on Wednesday.

She donned sandals on her feet and threw reflective aviator sunglasses on her face as she ran some errands.

The brunette left her long locks out and toted a large bag on her shoulder as well as her second child with fiancé Jamie Mazur.

Strong mother: Alessandra lugged a heavy bag on one shoulder and her child on the other

Noah looked adorable in the casual ensemble of a stripy top with black shorts, plus a blue cap and trainers.

His mother held on to his children’s easy sipping cup and gushed over him during their walk.

It seems the ample attention had continued from the day before when he celebrated his first birthday.

Keeping him close: The star opted not to use a pushchair for her offspring

Alessandra posted photographs of
their gathering on Instagram, complete with bunting decoration spelling
his name and his four-year-old sister Anja.

The
family appeared to have plenty of sweet treats around them and one snap
showed his parents pecking his cheeks as he tried a large swirly
lollipop.

Earlier on
Wednesday Alessandra was spotted wearing some patterned sweatpants as
she sipped on a hot drink and took a phone call.

Perking up: Ambrosio earlier got coffee at the Brentwood Country Mart

No cell phones! Alessandra got out to pump her
gas but the attendant insisted on doing it for her despite it not being a
full service garage

The chat was clearly quite important
as she continued to talk while getting petrol which is regarded as a
dangerous thing to do by the pump.

The star paced around her car while a male worker pumped gas for her.
