The couple has ended their relationship of more than two years, a source confirms exclusively to Us Weekly. Tisdale, 26, began dating music video director Speer, 29, in the spring of 2009, one month after she broke up with V Factory band member Jared Murillo.

"They had been on and off for a while. They tried to work it out but realized their relationship ran its course," a source tells Us.
