The highest bid on Ozzy Osbourne's suit currently stands at $2,175, but Justin Bieber's is the more popular on eBay.com - his clothing item is at $3,650. Both are expected to swell in value before the lots end.

Showing off the outfits on her daytime show The Talk earlier this month (Feb11), Sharon Osbourne said, "These outfits cost $30,000 each. Justin was sweating all day, so it's covered in his sweat.

"They are unbelievable outfits... They're signed by the guys and it smells just like Justin! The money goes to a great, great cause."

All proceeds from the sale will benefit the Sharon Osbourne Colon Cancer Program at Cedars-Sinai Medical Center in Los Angeles.
