I think I have found Olivia's Twitter user name as below:
@Olivia_Palermo
I presume this is hers because of the people following her, also, she has secured her tweets so we cannot read them. All the others using her name only tweet about things that are already public knowledge.
Twitter.com/TheRealOliviaP is definitely hers. Her friends like Peter Davis and Minnie Mortimer, and Vogue UK have confirmed for her. And you can tell it's her because she always talks about the events she's at/what she's wearing and then next day we get pictures of her at those same events she stated and candids of her in the outfits she said she was donning. She even talked about filming "Frock Me!" way, way prior to us getting pictures of them filming in Central Park pages and pages ago.
Olivia_Palermo may be her private account, I'm not sure, but I definitely think TheRealOliviaP is her open, and public account.
P.S. I think Olivia's outfit, the Chanel/Daryl K Leggings/Shirt with Bow is great. Yes, it's a tad stuffy, but I think she's trying to pull a Blair Waldorf of Gossip Girl, which is kind of fun.







and her hair is pure perfection!
