They’re expecting their first child together after tying the knot in June last year.
And Katherine McPhee looked radiant as she showed off her blossoming baby bump for the first time in a long-sleeved black top and leggings on Tuesday.
The actress, 36, appeared to be in good spirits as she went baby shopping while out for lunch with her husband David Foster, 70, in Montecito, California.

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

Foster has five daughters and has been married five times: to B.J. Cook, Rebecca Dyer, Linda Thompson, Yolanda Hadid and McPhee.
