Reality TV star Kristin Cavallari's family home has been foreclosed after her parents fell behind on the mortgage payments, according to U.S. reports.

The five-bedroom property appeared in Laguna Beach: The Real Orange County, which catapulted the California rich girl into the spotlight when the MTV reality series became a hit.

However, the star's father Dennis reportedly failed to keep up with payments on the $7.5 million he owed for the mortgage, according to TMZ.com.

The property was foreclosed and was sold at a public auction last month for $6.1 million.
