In Touch Weekly reports Justin Timberlake and Lance Bass’ relationship may have turned frosty after the two avoided each other when they both attended a pool party in the Hollywood Hills recently. “They didn’t acknowledge each other,” a source revealed.

“And they wouldn’t go into the pool at the same time.”

Another source speculated Lance’s jealousy over Mr Senorita’s solo success as the cause of the friction. “Lance always thought he was the best singer in the group and definitely not helium voiced Justin,” reasoned the source.
