From what I can tell, Chantal started her Twitter account on Feb. 17th. Her first post was something along the lines of she was just setting up the account and couldn't post anything until the show was done airing. Then she starts posting a couple days later. Weird. She is twitter friends with other bachelorettes as well as chris harrison so I'm sure they know about it.
On another subject...Brad apparently seems to tweet about the episodes as they are happening and on monday he tweeted:
Boca and I are still in touch #thebachelor (Boca is Chantal's dog)
That's the only piece of art in my place now. #thebachelor (in regards to Ricky's artwork)
Hope it's okay to share that.
