Get ready for an unexpected reunion on Shameless. We've heard that a fan-favorite Gallagher ex is about to return to the lives of TV's most dysfunctional family.

Now we can't reveal specifically who is making a big comeback - where's the fun in that? But we can give you a few hints.

It's been a while since we've seen the ex in question, and the breakup was not a good one, neither for the couple nor the fans. But it seems that time can heal all wounds, or at least mend them enough for this couple to give it another shot.

Catch up on all this week's Mega Buzz!

Our sources indicate that once the returning character breaks free of his/her current commitments, it'll be time to rekindle the romance with the Gallagher in question -- and the relationship is definitely a much-needed pick-me-up for both. (Let's face it, everyone in this family could use some good lovin'.)
