The remnants of two lives lived together? Or a silent admission that she misses what used to be?

Whatever the reason, Kristen Stewart stepped out Wednesday in what appeared to be Robert Pattinson's T-shirt. (The actor was photographed walking his dog Bear in the same shirt last year.)

And if wasn't the same one, it was an identical replica.

The actress, 22, who left her boyfriend and Twilight costar, 26, brokenhearted by having a tryst with her Snow White and the Huntsman director Rupert Sanders, gave no further hints as she traveled from Los Angeles to Toronto to attend a screening of On the Road Thursday at the Toronto International Film Festival.

While Stewart promotes that film, Pattinson will be at the MTV Video Music Awards in L.A., joining Taylor Lautner and other Twilight cast members to introduce 90 seconds of new footage from Breaking Dawn: Part 2 – in which Stewart, of course, also stars.
