Dated: Matt Leinart, Oakland Raiders (NFL)
When: September-October

So, apparently Emily Maynard is the bachelorette from the eponymous TV show, and, at the season's end, Emily got engaged to Jef Holm. But did she cheat on him with Raiders QB Leinart? That's the word on the street. The word is also that the engagement was a TV sham anyway, so the cheating was to be expected. But even in a sham, one needs a shred of dignity. When reports surfaced that Emily and Matt were sharing lovey-dovey tweets and texts (again), Holm got all aggro. The engagement is now off.
