Jessica Simpson is one proud mother as her 5-year-old daughter Maxwell graduated from preschool. The fashionista took to Instagram on Wednesday with adorable photos of Maxwell decked out in a blue cap and gown. "Spread your wings and prepare to fly for you have become a butterfly," Simpson wrote, quoting a lyric from Mariah Carey's 1997 song, "Butterfly." Simpson shared another photo of the tiny graduate jumping up and down barefoot with the caption, "Someone is excited for kindergarten!"
