Katharine McPhee, 37, looked like a grateful mother during her latest family outing. The singer was spotted sharing a sweet kiss with her adorable six-month-old son Rennie while going to lunch at Honor Bar in Santa Barbara, CA with her husband David Foster, 71. She was wearing a cute long gray and white summer dress that was sleeveless and paired it with a white baseball cap and white sandals as the bundle of joy wore a white patterned onesie.
