Was Chandra Wilson's awesome stint on Private Practice just the first of several such crossovers to come this season on Shonda Rhimes' sister shows? Here's E!'s latest ...

Q: I loved last week's Grey's Anatomy-Private Practice crossover with Bailey! She killed it. Is there anything good you can share on Grey's Anatomy or Private Practice?

A: I'm told by insiders that there should be at least two more crossovers before the season is through, though they have yet to hammer out specific details.

Who do you think should do the crossing honors?

As for one particular rumor going around - that there will be an upcoming plot involving for Justin Walker (Dave Annable) of Brothers & Sisters to cross over to Private Practice (Justin is now in medical school), a rep at ABC says that's actually not happening.

Aww. Too bad. But there are other good options.
