This probably won’t do anything to quell those Katherine Heigl exit rumors.

Sources confirm to me exclusively that L Word alum Janina Gavankar is joining the cast of Grey’s Anatomy as an intern. Meanwhile, relative newcomer Brandon Scott (Cold Case) is also checking into Seattle Grace as a junior McDreamy.

According to my Grey’s mole, producers are taking a wait-and-see approach with respect to the size of both roles. As a result, Gavankar and Scott will start off as recurring players. “Nothing’s been decided yet,” whispers the insider.

News of the new hires comes amidst buzz that Grey’s will likely upgrade Kevin McKidd to a full-time series regular before the season is out. As I mentioned in this week’s Ask Ausiello, the ex-Journeyman, who debuts in the Sept. 25 season premiere as a former Iraq doc with eyes for Cristina, is winning everyone over on the Grey’s set. Let’s see if Gavankar and Scott can do the same. (No pressure though!)

Initial reaction? Happy to see Seattle Grace get some (more) new blood? Or is the hospital too crowded as it is? Spill it in the comments!
