There’s another breakup in the Pratt family – and this time, just like her brother, Stephanie Pratt and former beau Josh Hansen are lashing out at each on Twitter.

“Another dysfunctional move by Stephanie pratt,” Josh Tweeted on Monday. “I was under the impression u had to be someones bf in order to get dumped.”

Stephanie, 24, snapped back at the motocross star, writing, “No josh hansen u were dumped stop acting like a child. Keep star f***ing ur way into hollywood. Now pls GO AWAY!!!!!!”

People confirmed the former couple’s split with Stephanie’s rep, who said simply that the couple “went their separate ways.”

Meanwhile, a rep for Josh, 26, told the mag he is “moving on” and claimed they were never official.

The former couple first met during last season’s final season of “The Hills” through series star Brody Jenner. They were spotted stepping out together after the MTV series wrapped last month.
