Chelsea's been over Adam for awhile now, but anyone who thinks she might fall back down his slippery-slope can think again.
When a fan told her Adam had attacked her on his Facebook page, Chelsea responded, "he's incredibly immature."
The fan offered to send her a screenshot, but Chelsea declined.
Another fan reported, "Saw your baby daddy partying in Minneapolis! Some friends said some not so nice things to him! But only cuz we love you! :)"
And maybe we're reading too much into her tweets, but this post makes it seem like Chelsea is so totally over him: "Sometimes, the best feeling isn't falling in love...it's falling out of love with someone who never really loved you."
