"Ace Knute channeling his inner Harry Styles on the way home from dinner tonight #HappyBirthday," Jess wrote of this cute pic in which the little guy shows off his One Direction-like coif.
Jess also shared a cute black and white family shot of her and her boys to wish the cutie a happy second birthday. It's not normal how gorgeous this family is.
Jess posted a similar snap last month for her daughter Maxwell Drew's third birthday on May 1, saying that she was "in complete denial" that her baby girl was getting so big. We are too!
And Maxi and Ace are about to get a new baby cousin, as Jess' little sister Ashlee Simpson Ross is expecting her daughter later this month. Calling it now—that baby's going to be just as gorgeous as these two kiddos.
Can you believe Ace is 2 already? Do you agree that Jess and Eric's kids are gorgeous? Tweet us @OKMagazine.
