Moving on -- and out? A moving truck was spotted outside Katy Perry's house on Wednesday, Feb. 26, shortly after news broke that she and boyfriend John Mayer had broken up again.

A source tells Us Weekly, however, that the truck just came and dropped something off. It was apparently empty when it left.

Perry, 29, and Mayer, 36, first went public with their romance back in 2012. They took a brief break that fall, and then again last March, but they ultimately reunited. In December, they released a romantic duet, "Who You Love," complete with a lovey-dovey video.

Recently, however, Perry has been spotted making solo trips to Milan and London. She's also busy preparing for her upcoming Prismatic tour -- which one source cited as a factor in their split.

"She's stressed about the tour," the source said of the "Roar" singer, who was previously married to Russell Brand. "They've been fighting. It is probably for the best, because she is going to be on tour for forever." Added another insider, "Not sure how long it will last this time, but, yes, it is off for now."
