Lance and Reichen Break Up - Again?

PARK CITY, UT -- The latest from the slopes of Sundance has it that Lance Bass and Reichen Lehmkuhl has called it quits. This is not the first time the lovebirds of eight months have broken up.

Eonline.com reports that Bass showed up solo at last Monday's Blender Sessions party at Tao. Later on, a source spotted him sulking at a party at the Village at the Lift's Heineken Lounge. He left the bash around midnight, after hanging there for a measly 20 minutes, the partygoer says.

Another source says Lehmkuhl is still in Park City but has told friends he is cutting his trip short and wants to get on the earliest flight out tomorrow.

Bass and Lehmkuhl were seen having breakfast together yesterday at the T-Mobile Cafe. "They didn't look too happy," an eyewitness says. "They were both on their BlackBerrys, and they weren't talking."
