Jessica Simpson  was all smiles in a photo she posted to Twitter  on Saturday night, enjoying a night out with her girls. Apparently she's found herself a strong support system  after splitting with Tony Romo last week , and she even got well-wishes from her ex Nick Lachey . He said , "I certainly have heard about her breakup and I wish her the best, as I’ve always done. Aside from that, there really is nothing to say." He also said they haven't spoken in years, so tell us — do you care what Nick thinks about Jessica's breakup?
