The Tenth Doctor and his Companion Rose Tyler will be reuniting in the City of Brotherly Love. In an announcement exclusively revealed to Blastr, we've learned that Doctor Who stars David Tennant and Billie Piper will be saying "Allons-y to Philly," and appearing together on stage at Wizard World Philadelphia Comic Con this May.

The appearance marks the first time Tennant and Piper have been on stage together in the U.S. at a fan event. Further, while Piper has been a guest at cons in the states, this is only Tennant's third North American convention ever (the second was Wizard World Raleigh Comic Con last weekend, and the first was his 2009 panel at San Diego Comic-Con -- which was more of a media appearance, and didn't include autograph and photo opportunities).

The news comes just two days after Tennant admitted on stage in Raleigh, and exploded Whovian fandom in the meanwhile, that "Rose was a girlfriend ... even if they didn't say it." The enormity of the announcement for fandom also increases when one considers 2015 is the tenth (yes, Tenth!) anniversary of the return of Doctor Who. Of course, beyond Doctor Who, talk at the con will most certainly include Tennant's casting as the villain in the upcoming Netflix show Marvel's A.K.A. Jessica Jones, and Piper's second season on Penny Dreadful -- not to mention Harry Potter, Broadchurch and Secret Diaries of a Call Girl.

Organizers for Wizard World Comic Con additionally shared that Piper would only be appearing on Sunday, so the duo's panel will be held that day. And in the interest of full disclosure, I have been hired previously as a guest and host for Wizard World cons -- though I'd be pretty psyched about this news regardless.

David Tennant and Billie Piper join Nathan Fillion, Stephen Amell, Hayley Atwell, Ben McKenzie, Kevin Conroy and more genre favorites for Wizard World Philadelphia Comic Con, held May 7-10 at the Philadelphia Convention Center. More information and tickets can be acquired at the Wizard World website.
