Lunch to go! Liv Tyler feeds baby Sailor his bottle while taking a stroll with fiance David Gardner

When it comes to multi-tasking, it seems Liv Tyler is an expert.

The mother of two expertly fed baby Sailor Gene his bottle as she carried him in a BabyBjorn sling on Thursday.

The eight-month-old faced out from the carrier as his mother held his bottle for him, keeping her other hand wrapped reassuringly around his waist.

Her calming presence seemed to do the trick - for despite the unorthodox feeding position, Sailor soon fell asleep.

Meanwhile Liv, 38, was accompanied on her stroll around New York by her fiance David Gardner.

The celebrity couple looked as chic as ever.

Liv kept things casual but sophisticated with a bright pumpkin-colored turtle-neck sweater, and some very tight skinny black jeans that emphasized her long legs.

Besides some low-top, classic Converse sneakers, the Lord of the Rings star completed her outfit with a rivet-studded black purse she wore across her body, and a pair of wayfarer-style shades. 

Her hair was up and back in a simple bun, and she looked to be sporting very minimal makeup.

David was on stroller duty, as he stuck close to his wife to be.

He opted for some blue trainers, jeans, and a chic military-inspired olive jacket over a grey T-shirt.
