If you’re wondering how close Justin Bieber and LMFAO are these days, Redfoo tweeted him a birthday wish via YouTube on his Twitter feed. Bieber appeared in the first number of their closing act, “Party Rock Anthem.” This is a long way from when they were doing songs at the beginning of their career for the reality shows Kourtney and Khloe Take Miami (“I’m in Miami, B*tch”—their first best-selling hit) and Jersey Shore (“Get Crazy”—which might as well reflect every cast member’s life choice on the show). They were nominated for the Favorite Pop/Rock Band/Duo/Group category, but Maroon 5 won.
