If you mean: Is she literally Megan with a dye job pulling some long con on Chris? then no.
But if you mean that she's his latest obsession, then yes.
Despite the criteria Chris wrote out on his "attraction signs" over the years, he was never too terribly particular about his women. He said he wanted a "cute girl", but some of the women he was seen with (such as
"The Hambeast" or
"The Wallflower") were objectively unattractive, and Chris didn't mind one bit. And he has never been looking for a relationship; he has always just been looking for a willing (or at least
non-objecting) hole to put his bent duck. He is too self-centered to have a true emotional relationship with another person. If a woman is willing to spend time with him, that's enough for him to fall for her -- nothing else really matters.
