Jessica Simpson has finally taken the plunge and joined the majority of the celebrity world on Instagram. Earlier this week the singer tweeted a link to her new account and wrote: “It’s official! I’ve just joined Instagram before it’s not cool anymore!” But it seems she’s a natural as she has already uploaded a number of photographs including one of her newly-engaged sister Ashlee and future brother-in-law Evan Ross. Jess also posted a cute picture of her one-year-old daughter Maxwell. She captioned it: “Love this lil lady more than anything!” Jessica with sister Ashlee and her fiancé Evan Ross. The singer also shared a mother-daughter snap with her daughter Maxwell. [Images via Instagram/ jessicasimpson1111]
