Jessica Simpson Shares Beyond Adorable Photo Of Daughter Maxwell On Her 3rd Birthday

Jessica Simpson's daughter, Maxwell Drew Johnson, is hands down one of the cutest kids in Hollywood, and we can't believe how big she's getting.

Her mother can't believe it either, judging by an adorable photo she shared via Instagram on Monday:

May 1 my Maxi Drew turned 3.... I am in complete denial

Simpson and Eric Johnson welcomed Maxwell to the world back in 2012 and added another member to their family a year later, when Simpson gave birth to son Ace Knute Johnson on June 30, 2013. Their overwhelming cuteness dominate's the 34-year-old singer's Instagram feed, and we're not complaining:
