Katherine kept things casual for the outing, donning comfortable sportswear which covered her growing stomach.

She kept her to a minimum, but did don some sunglasses and a face mask as well as wearing her cute dog in a light grey sling across her body.

The brunette tied her long tresses back into a low ponytail and added a navy blue baseball cap to complete her ensemble.

David also cut a relaxed figure in light denim jeans and a t-shirt, with the record producer opting to match his wife with a similar choice of hat.

During the outing David was seen browsing real estate magazines while waiting for their table at dining spot the Honor Bar.  

While mom-to-be Katharine passed the time by browsing baby stores, leaving The Nurture Cottage with a large white shopping bag full of purchases.

The couple were married at the Armenian Church of St Yeghiche in South Kensington, London on June 28 last year.
