Stephanie Pratt and her boyfriend, Josh Shepherd, are modeling their relationship after that of the reality star's brother and his wife.

'The Hills' Cast: Where Are They Now?

Six months into their relationship, Stephanie, formerly of MTV's The Hills, claims she and Shepherd look to her older brother, Spencer, for relationship advice.

"We've had the chat but my brother Spencer and Heidi are the best example of it working out. That's what I think about," Stephanie explained to OK Magazine on Thursday.

On The Hills, Spencer's relationship with Heidi Montag was put to the test when he allegedly began pursuing her co-star, Audrina Patridge. However, the pair continued to date and eventually became engaged in Santa Barbara, Calif. Years later, they walked down the aisle in a made-for-TV wedding, which aired on The Hills.

While Stephanie and Shepherd may not be preparing to walk down the aisle quite yet, they are both dedicated to the relationship in the same way her brother is with Montag.

"The only time people have relationship problems is when one of them cheats on the other and that's not happening for us," Shepherd explained. "I don't really have anything to worry about."

Earlier this year, Stephanie appeared on an episode of Millionaire Matchmaker, during which her brother and wife attempted to help Patti Stanger find her the perfect match. Although things didn't work out for Stephanie and her match, she found love with Shepherd a short time later.
