The brunette actress has been seen pushing a baby pram while out shopping in North London.
Going make-up free for the outing, Louise Ford looked stunning as she covered up in a grey wool coat, along with a bright orange hat to fight off the December chill.
Pushing a yellow pram, 34 year old Louise hit the shops and was seen buying baby clothes on Hampstead High Street in the capital.
The actor’s partner Louise was spotted with a ‘sizeable baby bump’ during a shopping trip in North London.
A source told the Sunday People: “Rowan and Louise are over the moon and can’t wait for their new arrival.
“It’s a very happy time for them both.”
Rowan already has two grown up children, Ben, 23, and Lily, 21 who he had with his ex-wife Sunetra Pastry.
They were married for 25 years, before splitting from Sunetra in 2014 after she cited irreconcilable differences.
Rowan first began dating Louise after they met in 2012 when they acted in a West End comedy show together.
Louise is well-known for her roles in The Windsors and Crashing on Channel 4.
