Former 'N Sync singer Lance Bass has sparked speculation he is homosexual and dating Amazing Race reality TV star Reichen Lehmkuhl after the pair were spotted partying at gay bars together.

Since the boy band leaped to fame in 1997, his band mates Justin Timberlake, JC Chasez and Joey Fatone have been romantically linked to a host of female celebrities, but Bass' love life has remained low-key.

The New York Post newspaper reported last week that Bass and Lehmkuhl - who won the 2003 prize in the Amazing Race with his former lover Chip Arndt - were together at gay bar Atlantic House in Provincetown, Massachusetts.

Kevin Naff, managing editor of leading gay and lesbian newspaper The Washington Blade, tells ABC News, "Perhaps the Post is not outright saying Lance is gay. But by implication, we can all easily connect the dots.

Naff says several bloggers on the newspaper's website have spotted Bass at a series of parties in Provincetown, a seaside gay hotspot.

He adds, "If privacy is what Lance wants, that's something that's easy to have. But if you're Lance Bass, and you're going to the gayest town on the gayest day of the year and going to gay parties, you have to expect something."

Bass' spokeswoman Cindy Owen and Lehmkuhl's spokeswoman Mara Santino have refused to comment on the Post reports.
