Christina Aguilera just put her 8,900 square foot Beverly Hills mansion on the market for $13.5 million, which she purchased from Sharon and Ozzy Osbourne back in 2008, and X17online was surprised to see the home's previous owner visiting the property yesterday with a real estate agent in tow!

Did Sharon suffer seller's remorse all this time and now wants the famous property, that was featured on her MTV hit show The Osbournes, back?

Sharon and Ozzy originally bought the place in 1999 for a steal at $3.9 million. They later sold to Xtina for $11 million after Ozzy declared, "I don't want to stay in that house any more... The house holds bad memories for me because it reminds me of the terrible time Sharon got cancer and of times when me and the kids were doped out of our minds."

Considering that Christina's career has taken a hit (her national anthem flub, her box office disappointments) not to mention her personal life has hit a snag, could the mansion be cursed? And if so, why would Sharon want it back?
