Kimberly Stewart and MTV's Laguna Beach hunk Talan Torriero have called off their engagement.
The couple originally announced their plans to wed on Nov. 15, after only a couple of months of dating. But apparently they’ve both had a change of heart.
"It was just too soon to enter into a lifelong commitment," the couple's reps said in a joint statement to PEOPLE. "It is better to have a brief engagement than a short marriage. The couple continue to share their time together and remain open to whatever the future may hold."
The first public hint that Torriero, 19, and Stewart, the 26-year-old daughter of British rocker Rod Stewart, might be an item came only weeks ago when the pair were spotted in the backseat of pal Paris Hilton's Bentley in L.A. So the couple's engagement came as a shock – to many people. "It definitely took me by surprise," Stewart’s mom, Alana Stewart told PEOPLE. "She's an impulsive girl. What can I say?"
On Nov. 16 the pair picked out a 5-carat diamond ring from L.A. jeweler Neil Lane. That night, holding hands as they walked into the Xbox 360 launch party in Beverly Hills, they broke the news to friends, including Hilton and her sister Nicky.
A friend of Torriero's told PEOPLE at the time: "He told me he really likes her and they're having a good time."
Torriero, an aspiring musician and actor, just wrapped a role in the thriller Driftwood.
Stewart, who was for a time rumored to be a replacement for Nicole Richie as Hilton's partner on The Simple Life, was once engaged to musician Cisco Adler.
