Following a two-week hiatus, Glee returns with a new episode tonight.

It will include a diva-off between Kurt and Rachel over who gets to take the lead on "Defying Gravity," which should be enough to guarantee record ratings on its own.

But E! News recently spoke to show sources that confirmed other exciting storylines and numbers to come on the comedy.

Here's a look at a few likely spoilers:

A New Relationship: "[This week's] ep kind of sparks it," Kevin McHale (Artie) said of a burgeoning romance. "I think Tina and Artie will be together. I think they will be a couple for a long time."

Parents On the Way: Said a source: "Next week we'll meet Quinn's mom and dad - and so will Finn. The glee club has a new assignment to use songs to express feelings they can't otherwise get out, and needless to say, the Fabrays don't appreciate Finn's interpretation of said assignment.  We also get to spend a little more time with Finn's mom."

As always, we'll recap and review tonight's installment, adding all new singles to our Glee music section. Enjoy the return of the most entertaining show on TV!
