It appears as though the prayers of Chloe Sullivan fans may have been answered.

According to an article from TVLine.com, Michael Rosenbaum will now be joined by Allison Mack in the final episode of Smallville. Here's what the site had to say:

Fans of Smallville‘s Chloe were a bit disappointed to see their girl quietly exit stage left at the end of the February 25 episode, to work (off-camera!) at the Star City Register. But since Allison Mack only signed on for five episodes this season and that was the last of ‘em, what can you do? Well, for one, you can have Mack back. Though neither The CW nor Warner Bros. TV is confirming anything about the two-hour series finale beyond its May 13 airdate and Michael Rosenbaum’s encore as Lex, a well-placed source tells me that Mack – also an original cast member – sneaked back to the set and will be a part of the grand send-off. And that, friends, is super.

As the article indicates, there is no official word from The CW or Warner Bros. on Chloe's return so, for now, take this news as strictly a rumor.
