Conrad and Jenner last October
Less than a month after Brody Jenner told PEOPLE that he and The Hills
star Lauren "L.C." Conrad were "seeing each other,"
the two have split up.
"We're not together anymore," Jenner told a source on Thursday at the launch party for the new furniture collection at Minotti in Los Angeles.
The news was echoed by his mother, Linda Thompson, who told PEOPLE at the Environmental Media Awards last week, "I think Brody's pretty single right now. He's on his way to Miami. Bikinis, thongs. I think he'd better be single right now."
Conrad's rep, Nicole Perez, had no comment.
On Oct. 18, Jenner, 23, revealed that he and Conrad, who got her start on Laguna Beach,
had started a romance. "I don't know what you consider dating, but we're seeing each other, we're having a great time with it. She's an amazing girl."
Conrad, however, was coy about her relationship with Jenner at the time, saying only, "He's a nice guy."
In early October, Jenner split from Nicole Richie, whom he started seeing in August, just weeks after ending his year-and-a-half long relationship with Laguna Beach
star Kristin Cavallari, Conrad's nemesis on the MTV reality show.
from her fellow Laguna Beach
alum Jason Wahler in August.
