Redfoo and Psy — the new LMFAO? Looks like Foo has found an energetic “Gangnam Style” stand-in for his partner SkyBlu after announcing this week the rap duo is “taking a break.” Redfoo partied with the Korean rap star at Tao Las Vegas Saturday, and both flexed their trademark dance moves until the early morning. The “Gangnam” superstar had dinner at Tao and invited Redfoo to stop by. Psy “got the party going early and got Foo shuffling by getting him to do sake bombs,” said a source. The duo later hit Tao’s nightclub, where Psy performed his hit “Gangnam Style” for the crowd. Then Foo and Psy cleared space at their table and had a “shuffle off,” where both performers showed off their famous dance moves.
