Jessica Simpson's baby overloads Internet with cuteness

jessica-simpson-maxwell-eri.jpg Jessica Simpson 's fiancé, Eric Johnson, celebrated his 33rd birthday with the best gift ever: their baby daughter, Maxwell.

"Last year at Daddy's party, Maxwell was in my belly," Simpson tweeted . "This year she's in my arms!"

Their little bundle of joy -- seriously, have you ever seen a more joyful baby? -- has grown so much since Simpson tweeted a picture of the threesome celebrating Fourth of July.

Who needs a birthday cake when you have such sweet photos?
