While Us Weekly reported Robertson moved in with The Bachelor star and his two roommates in San Francisco last month after packing up her belongings and traveling almost 400 miles upstate from Santa Monica, CA, Flajnik has insisted that wasn't the case.
"We were moving my sister and her boyfriend," Flajnik toldNewsday, saying the situation was a misunderstanding after the couple was photographed carrying boxes and other items into his apartment building.
The Bachelor couple -- who had called off their engagement while the show's sixteenth season was airing but then decided to get back together and get re-engaged during The Bachelor's After the Final Rose special -- is apparently in no rush to get married although they attended a runway show for designer Mark Zunino's bridal collection in New York City on Monday.
"We don't have a date," said Robertson, a 28-year-old model, adding that she has been good friends with Zunino for about five years and came to the show with her fiance to show their support.
Once the couple does decide to set a wedding date, one thing seems likely -- they won't be broadcasting the ceremony on TV.
"Television didn't work out so well before," Flajnik told the website. "We'll see. Everything's gone so fast so far. We want to take things slower."
Robertson got engaged to the 29-year-old winemaker from Sonoma, CA, when he selected and proposed to her during The Bachelor's sixteenth-season final Rose Ceremony, which was filmed on November 16.
