Cuteness overload! Just a few days after Jessica Simpson tweeted a photo of her 19-month-old daughter, Maxwell Drew Johnson, showing of her "boo boo," the fashion designer shared another precious picture -- this time on Instagram.

"Love this lil lady more than anything!" Simpson, 33, captioned the close-up picture giving her daughter a kiss on the cheek.

Maxwell's face broke into an adorable grin for the picture, and the little tot certainly shares her mom's platinum blonde hair color. Simpson is also the proud mother of 6-month-old son Ace Knute with fiancé Eric Johnson.

"It's official! I've just joined Instagram before it's not cool anymore!" she wrote.

In addition to posting the second image of her baby girl, Jessica also shared a "family moment" with her younger sister Ashlee Simpson and the pop rocker's new fiancé Evan Ross. 

In the picture, Jess is grinning while wedged in between the two lovebirds and showing off Ashlee's new engagement ring. Ashlee, 29, announced on Monday, Jan. 13 that she was engaged to Diana Ross' 25-year-old son.
