The Las Vegas Sun reported Thursday that the reality series returned in October to Las Vegas, where filming continued through January.
The show first came to Las Vegas for its 12th season in 2002. The cast lived at the Palms Casino Resort during filming.
Previous editions have focused on young strangers living together in front of cameras in New York, Los Angeles, Miami, Boston, London and Paris.
The new season premieres in March.
The roommates were filmed living in a four-bedroom suite at the Hard Rock complete with hot tub, bowling alley, pool table and bar.
The hotel-casino is separate from the restaurant chain with the same name.
