Jessica Simpson and her fiancé Eric Johnson were "disappointed" about the Osbourne fire.
The 64-year-old rocker singed his hair and injured his hand while trying to put out the blaze at his family's Beverly Hills mansion, his wife Sharon said last week.
Jessica and Eric, who are currently expecting their second child together, were originally keen on purchasing the multimillion dollar property.
Apparently they are now wary to move forward.
"When Jessica and Eric heard about the fire they were as equally as disappointed as the Osbournes," a source told Radar Online.
"They were planning on making an offer on the mansion somewhere in the region of $12 million, because they felt it was the perfect family home.
"Now, they're going to have to assess the damage before committing, even though they heard it is pretty minimal.
"Jessica does have her sights set on the property but she is looking elsewhere again.
"She's also a believer in fate and is wondering if the fire was a sign that she shouldn't buy it and wait for something else to come on the market.
"It's a shame for Sharon and Ozzy - they were ready to sell."
The local fire department was called to the residence at approximately 4:25a.m. after the couple fell asleep before extinguishing a candle which exploded in its glass vase and sparked a small fire in their living room.
Firefighters were able to extinguish the blaze before it caused significant damage.
