Ashley Tisdale and Scott Speer are back on!

The Hellcats actress and her ex-boyfriend went on a movie date together Sunday in West Hollywood and sources confirm to Us Weekly they're dating again.

Tisdale, 26, tweeted a photo of herself and Speer posing in front of a Step Up Revolution movie poster, which Speer, 30, directed.

"Look what Scott Speer and I found Step Up Revolution," she wrote with the photo. Speer also tweeted the poster, writing, "Wow. Purple does Pop."

After dating for over two years, Tisdale and Speer broke up in December 2011. A source told Us Weekly of the split, "They had been on and off for a while. They tried to work it out but realized their relationship ran its course." Tisdale began dating Martin Johnson in January, but the actress has been seen spending time with Speer again.

Sources confirmed to Us Weekly that Tisdale and Speer have, indeed, reconciled.
