Kaley Cuoco showed off her pregnancy glow in a series of adorable maternity snaps. The Big Bang Theory actress - who recently celebrated her 37th birthday - took to her Instagram on Thursday to post photos of her and partner Tom Pelphrey as they celebrated their upcoming bundle of joy. In one snap Tom was seen placing a kiss on the star's growing baby bump, as Kaley joyfully looked at the camera.

The California-born star - who's expecting a baby girl - looked chic in a long-sleeve brown sweater and sported a floral skirt.

Her blonde tresses and bangs were styled straight for the day. Meanwhile the dad-to-be looked stylish in a baby blue sweater, black pants and matching shoes.

In another one Tom was seen embracing her from behind, with both of them laughing in joy. Kaley's 7.6M followers were thrilled with the adorable photos.
