It seems that there's trouble in the fairytale romance of Heidi Montag and Spencer Pratt: OK! has learned that the reality starlet has walked out on her husband after fewer than 18 months of marriage.
Things have been rocky between the pair recently, and Heidi even fired Spencer briefly as her manager two weeks ago.
But, according to sources, now it's their personal relationship that's breaking down.
It's not yet clear what caused the split. But according to an insider, Heidi hates having to admit that her Spencer-loathing former best friend, Lauren Conrad, had a point about her blonde beau.
But adds the pal: "She was right, he is a selfish jerk."
Another source close to the couple confirmed: "She's moving out of her house and away from Spencer."
Spencer is said to be living at the L.A. home alone, while Heidi is staying with friends.
MTV has not responded to OK!'s request for comment at this time.
