Dreams really can come true. Tomorrow, Tori Spelling returns to 90210 as Donna Martin, making old school fans squeal like we’re in high school again. Donna surprises Kelly (Jennie Garth) and Silver (Jessica Stroup) when she shows up at their door, straight off a plane from Japan where she has been working on a new fashion line. As an added bonus, Diablo Cody, the Academy Award winner and writer of Juno, is also appearing on the show as herself. Apparently, Cody hires Donna to design a dress for a movie premiere and Donna shows up at the event with her to make some last minute alterations.

Also this week, Annie (Shenae Grimes) and Dixon (Tristan Wilds) decide to spend their spring break on a road trip to visit someone from Dixon’s past, while Ethan (Dustin Milligan) decides to step out of his bubble and volunteer with Habitat for Humanity. Naomi (AnnaLynne McCord) joins the Habitat build after learning that Liam (Matt Lanter) is also attending, but is clearly out of her comfort zone.

Here’s a sneak peek at Tori’s return to everyone’s favorite zip code!
