Brad Paisley has been using Twitter since May, keeping fans updated on his day-to-day happenings, and even posting pictures of everything from playing Pac-Man on his iPhone while on an airplane to hanging with Kevin Jonas of the Jonas Brothers.

He has also of late been musing about the virtues of various superheroes, writing of cartoon character Mighty Mouse: "he fights cats, he's a mouse but he's mighty. Incredible upper torso development, smart, so complex." And of Green Lantern, Brad notes: "He puts on a ring and gets superpowers. When in the history of earth has a man putting on a ring ever not LOST his powers?"

It's no wonder all of this tweet-ing seems to have become the cause of some concern for Mrs. Paisley. Just yesterday, Brad posted a tweet reporting that his wife, Kimberly Williams-Paisley, had coined a new term: "twittow" -- referring to "a woman abandoned by a male companion who is continuously using the webservice Twitter."

An hour later, guess who signed up for her own Twitter account? Yep, Twitter users (including her pre-occupied husband) can follow the actress at her official page. But she may need some instruction from her in-home expert -- Kim admits in one of her first posts that she has "twitter jitters."

We can't wait to find out what term she'll coin for husbands who are unnaturally obsessed with cartoon superheroes!
