Rachel Bilson & Hayden Break Engagement Filed under ( Break-Up, Hayden Christensen, Rachel Bilson )

Rachel Bilson and Hayden Christensen have officially ended their relationship, her rep confirms Us Magazine.

"Yes, the engagement is off, therefore, so is the wedding," her rep tells Us.

In June, a source told Us the couple -- who co-starred in the 2008 action flick, Jumper -- were "taking about a month off" to evaluate their relationship. “They’re taking a break,” the insider added.

Around the same time, Bilson flashed a ringless finger to Us on the red carpet of a THQ/Take No Prisoners event in L.A. When asked how wedding plans were going, she said, "No, no plans" and pointed to her bare hand. "No nothing."

Christensen, 29, and Bilson, 28, announced their engagement in February 2009.

Stephanie Pratt & Josh Hansen: Twitter Breakup Filed under ( Break-Up, Holly Madison, Josh Hansen, Stephanie Pratt, Twitter )

Spencer Pratt isn't the only one in his family experiencing some breakup drama.

His sister Stephanie Pratt and her motocross beau Josh Hansen "went their separate ways," her rep confirms to PEOPLE.

There are no further details about the split, but it seems that the relationship did not end on amicable terms.

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

Pratt, 24, and Hansen, 26, first hit it off after meeting through Brody Jenner at a Hollywood nightclub on one of the last episodes of The Hills. The duo continued hanging out post-Hills and walked the carpet together at the show's series finale last month.

In response to Hansen's Tweet, Stephanie Tweeted, "No josh Hansen u were dumped stop acting like a child. Keep star [expletive] ur (sic) way into Hollywood. Now pls GO AWAY!!!!!!"

A rep for Hansen says the two were never an official item and that the racer is "moving on." Meanwhile, Hansen has kept himself busy by Tweeting to former Girls Next Door star Holly Madison.
