Precious cargo on board! Liv Tyler and baby Sailor take to the streets of New York to run some early morning errands 

While most celebrities were still nursing a sore head, Liv Tyler was up early going from party princess to mom mode.

The 37-year-old star spent Monday evening being the belle of the very stylish ball at a Stella McCartney fashion show, however, the next day she was busy running errands around New York first thing with son Sailor.

Deciding against getting a celebrity-favoured chauffeur ride around town, the star headed out in the West Village on foot with her five-month-old strapped to her chest in a Baby Bjorn.

Setting a cracking pace, with what appeared to be her nanny trying to keep up with the pram behind her, Liv dashed across the busy streets.

Making sure her little man was not too bothered by all the loud sounds of Manhattan, every so often the Leftovers star tenderly stroked him on the head.

For her day of errands, a makeup-free Liv took to the streets in a flowing paisley print dress.

The frock had a very Seventies vibe with its billowing sleeves and green print.

Nail off duty style with a pair of cut out sandals

She may have just given birth to her second child, but you won't catch Liv Tyler strolling around in mom jeans. The Lord of the Rings star was pictured with her two sons around NYC, and her laid back sartorial sense was anything but lacking.

The rock and roll heiress wore a casual cool all-black ensemble and a pair of Alaïa laser cut sandals. How's that for off duty style?

The circle patterned shoes come in a variety of colors and a there's a heeled version as well. A hit among the celeb set, the Tunisian designer's coveted footwear have been worn by Rihanna, Alicia Keys, and Mariah Carey to name a few.

The star accessorised her look with a pair of strappy flat slip on sandals and classic Ray-Ban Wayfarer shades.

Little Sailor meanwhile, was dressed in theme his name suggests, wearing a pair of blue cropped pants, blue socks and a white long sleeve shirt.

Liv's flowing feminine look was a departure from her striking pant suit ensemble that she wore the night before at the Stella McCartney Spring 2016 Resort Presentation.

The star wore chic matching black skirt and pants featuring a pattern made from vibrant coloured feline predators.

Besides popping out to the odd fashion event, Liv has been spending all her time with her growing family of late while her show The Leftovers is between seasons.

The Armageddon actress is also mother to 10-year-old son Milo from her previous marriage to Royston Langdon.

Sailor's father is the actress' fiance Dave Gardner, who also has a seven-year-old son Grey with his ex-wife, actress Davinia Taylor.

Liv has been wearing a dazzling ring on the fourth finger of her left hand but has yet to confirm whether she and David are engaged.
