Spencer (Troian Bellisario) and Toby (Keegan Allen) have quickly become one of the cutest couples on Pretty Little Liars, but unfortunately, they may not last all that long. We were shocked to hear this news considering Troian said Spoby is true love and Spencer’ parents will finally accept Toby next season. However, let's be realistic - most couples don't last forever on PLL.

Troian told Zap2It that Spencer and Toby will be together for a while, but it would be boring if they were always happy. “Something has to change otherwise it's going to start to strain their relationship," she explained. And by something, she means someone: Wren (Julian Morris).

We know Wren will return to Rosewood and most likely complicate things for Spencer. Her family already hates him for hurting Melissa (Torrey DeVitto), and Toby won’t like him either because he’s competition. Troian didn't reveal much about this probable love triangle, but hinted, “I can tell you that Toby's not too thrilled that he's back."

Do you think Spencer and Toby will stay together or will she leave him for Wren? Oh, the drama!
