    Forget Throwback Thursday! This is our favorite photo of the day.

    Hilary Duff took to Twitter today to share a photo with her 2-year-old son Luca and the super-sweet shot of the mother-son duo is sure to make you say, Aww.

    "[Kissin] like we mean it. (MC gets photo cred for this 1)" the mother of one captioned the twitpic with a kissing emoji, instantly proving that she and Luca are the world's most delightful duo. 

    Duff and her son are killing us with cuteness while sharing a smooch in the shot, as little Luca reaches up and adorably grabs his mama's head to pull her in close.

    The former Disney star presumably gave her ex, Mike Comrie, a photo credit for the pic, providing evidence once again that the former couple is nothing but amicable.

    Luca most recently celebrated the big 0-2 and the proud mama shared a sweet photo collage of her son in honor of his 2nd birthday on her social media page.

    "You make each day better and better Luca Cruz .... The brightest star," Duff captioned the pic-framed photo, which featured a slew of precious pics of little Luca, including a shot with the singer's ex.

    In January, Duff made headlines when a rep for the actress announced her split after three years of marriage from the former NHL hockey player. Despite the breakup, the two have maintained an incredibly amicable relationship for their son and recently enjoyed a "modern family" vacation.
