Pregnant Keri Russell shows off her growing baby bump in striped top as she steps out with boyfriend Matthew Rhys and daughter Willa

Keri Russell is ready to welcome her third bundle of joy in to the world soon. 

And the 39-year-old actress - who is due to give birth this spring - was spotted enjoying a stroll on Sunday in Brooklyn, New York with boyfriend Matthew Rhys and her four-year-old daughter Willa Deary.

Carrying a couple of hot drinks in each hand, the heavily-pregnant brunette looked relaxed and effortlessly stylish in her go-to maternity wardrobe.

Keri flashed her bump in a loose-fitting striped top and wrapped up warm with a long dark green woollen-effect coat.

Making sure she had enough room for mobility, she wore a pair of slightly baggy black leggings and grey worn-in shoes.

Her boyfriend and Americans co-star Matthew carried weight of his own as he gave Keri's daughter Willia a piggy-back ride.

Braving the NYC chill, the 41-year-old actor wore a plain black short-sleeved top with a pair of classic blue denim jeans.

Gearing up to become an older sister, Willa - who also has a big brother, seven-year-old River - seemed shy as she hid behind her mother's boyfriend and onscreen husband.

River and Willa are Keri's children from her previous marriage to Shane Deary. They ended their seven-year marriage in 2013. 

Meanwhile, Keri and Matthew's latest sighting is another in a long line of family strolls the duo have embarked on in recent times.

Just last week, Keri surprised everyone by showing just how large her baby bump has grown as she stepped out with her boyfriend last week.

The Felicity vet was wearing a tight blue T-shirt under the same green coat that revealed she is quite far along.

Spring into some sunnies by Oliver Peoples like Keri

Teaming a pair of black sweats with an oversized moss green cardi, Keri Russell looked super comfortable in this get-up as she ran some errands. Exactly what you want to wear when you're off duty and 7 months pregnant, right? She topped her outfit off with a pair of chic blonde framed sunglasses from Oliver Peoples which we're majorly coveting.

It might not be sunglasses weather quite yet but there's no harm in getting ahead of the game is there? This pair from Oliver Peoples are a great everyday style and would go with everything from flippy floral dresses in summer to jeans and cozy knits right now.

Head over to Saks Fifth Avenue and pick up this pair now that Keri is wearing. If you'd rather find yourself something a bit less spendy, then take a look through our edit below. We've rounded up similar styles to Keri's at a fraction of the cost from Topshop, Asos and Urban Outfitters.

Keri also showed off her slim pins in a pair of skintight white jeans.

The looker was holding a beige supermarket sack and had her cell phone in the pocket of her beloved green coat, which she had worn the day before.

Rhys looked stylish in a denim jacket over a maroon shirt with grey slacks and beige suede lace up shoes. A grey cap looked borrowed from Brad Pitt.

Oddly there was no PDA between the couple who for many months in the beginning of their relationship denied they were an item.

They were repeatedly asked if they were romantic and always said no, even though a member of his family claimed they were an item.

They are still very quiet about their relationship.

The actress was all smiles as she stepped out to lunch with friends at Locanda Verde restaurant in New York City on Monday. 

The star, who hits the big 4-0 on March 23, did her best to keep the brewing baby warm in a thick green tweed coat.

She finished her cute outfit in a striped top, white jeans and slip-ons, not forgetting her shades on the sunny Tribeca afternoon. 

There was no sign of the baby's dad, on and off screen partner Rhys.
