Lauren Conrad has broken up with her boyfriend, former "My Boys" star Kyle Howard, who the reality star has been dating since 2008.
Conrad, 24, managed to keep her relationship with the 32-year-old actor a secret from MTV's cameras while filming "The Hills," but it was one of the reasons she left the hit show in 2009. An insider told E! Online that the breakup was mutual and there were no third parties involved.
In January, Conrad denied that she was engaged to the actor.
Conrad announced in September 2010 that she was working with MTV on a new reality series which would not involve her boyfriend Howard, but instead concentrate on her work as a fashion designer.
The project was scrapped in February and was dubbed too "high brow" for the MTV audience.
"We sold a show to MTV, filmed it and are really proud of the final result," Conrad had said in a statement.
"MTV felt the subject matter was too high brow for their audience and offered me the opportunity to change the show by incorporating more of my personal life," she said. "We agreed going into the project that this show would be an aspirational one, focusing on my career and my goals and not my personal relationships. We delivered the show that we sold and are sorry MTV didn't feel their viewers were savvy enough to appreciate it."
Conrad began her TV career at age 17 with the MTV show "Laguna Beach," named after her hometown in Southern California. She went on to star in its spinoff, "The Hills," which depicted her life in Los Angeles and also starred real-life "villain" couple Heidi Montag and Spencer Pratt. The show ended in July 2010.
The fashion designer debuted her line, LC by Lauren Conrad in 2009. She also developed the LC Lauren Conrad for Kohl's and the Paper Crown fashion labels.
Conrad is also a New York Times best-selling author and has published four books including, "L.A. Candy," "Sweet Little Lies," "Sugar and Spice" and "Lauren Conrad: Style." She has also launched websites like LaurenConrad.com and TheBeautyDepartment.com.
She told OnTheRedCarpet.com in October that she wants to develop her L.A. Candy novels into a film or a television series.
