Safe to say this shot just made our Tuesday afternoon. Hilary Duff took to Twitter on Monday to share yet another aww-worthy shot with her 2-year-old son Luca Comrie and in typical Duff fashion, the proud mama is killing us with cuteness. The 26-year-old singer captioned the adorable pic in which she’s soundly sleeping with her little boy, “This is everything.” Of course, Hilary is no stranger to sharing sweet shots of Luca. Earlier this month, she posted an Instagram video of her son bursting into a fit of giggles while watching A Bug Life’s, captioning the clip, “baby giggles are the best.”
