Joining the ranks of Miley Cyrus and Shanna Moakler yesterday, “American Pie” star Shannon Elizabeth and her boyfriend of almost 2 years, “Dancing With the Stars” mainstay Derek Hough, have become the most recent celebrity couple to announce their dissolution via the Twitterverse.

According to a tweet sent out Friday night, Elizabeth writes, “Hi everyone-we wanted you all to know directly from us that Derek & I have decided to end our relationship as boyfriend & girlfriend…” She adds, “however, we love & care about each other very much & will remain friends & in each other’s lives.”

The couple, who moved in together last October, began dating in 2007 after being paired with each other on season 6 of “Dancing With the Stars.” Separated by a 12 year age difference, 23 year-old Hough said of living with 35 year-old Elizabeth – along with three of his “Almost Amy” bandmates, “[Shannon] was like, ‘They can stay here until they find a new place,’ and, once they started talking about finding a new place, Shannon and I were like, ‘Wait, we’re going to miss them when they go.’ And we were like, ‘Why don’t you just stay here? We’ll make rooms up for everyone!'”

Hmmm….what could have possibly gone wrong with such an ideal living/dating situation?
