Hey there, I'm Karli Bulnes. The American Music Awards were jam-packed with must-see moments. Check out our top three in PopSugar Rush. JLo's Sexy Stripteaase "Let me introduce you to my party people..." Jennifer Lopez revealed not one, but two revealing costumes during a striptease for her performance with Pitbull. The nude and glittery creation looked a whole lot like Britney Spears's outfit from the 2000 VMAs, but J Lo made it her own. Either way, JLo looked amazing as she danced away with the Favorite Latin Artist award, and gave an honest acceptance speech about her trying 2011. Jennifer Lopez: "It's been a really amazing year in so many ways. It's been up and down and just exciting and overwhelming./I just want to thank my family most of all. My beautiful babies who inspire me every day to be a better person and be better at everything that I do." Ms. Lopez's ex, Marc Anthony also performed with Pitbull just minutes later. Taylor and Selena's Sisterly Love "I love you Selena, my little sister I never had!" A shocked Taylor Swift took the stage three times to accept trophies, including the big Artist of the Year award for a second time in her career, and after thanking her devoted fans, she thanked good friend Selena Gomez, who was seen singing along with Taylor to Super Bass and dancing to Maroon 5 and Christina Aguilera's performance. "moves like Jagger, you got the moves like Jagger, you got the moooooves like Jagger." Justin Gets to Shuffling "Go Bieber, go Bieber, go Bieber..." (and bring music under) After sharing a sweet kiss with girlfriend Selena Gomez on the red carpet, Justin Bieber surprised the crowd by coming out with LMFAO to close the show with his shuffling skills. He performed his holiday song earlier, but changed into this colorful ensemble to do the famous dance with Selena watching on. Bieber's appearance was the most unexpected move of the night — that is until David Hasselhoff stripped off his pants to do the wiggle with the group. Lindsay stand-up: Adele led the pack with four nominations this year. Her current hit "Someone Like You" is such a pop-culture phenomenon SNL even built a skit around it earlier this month. Overall, the big winners were Taylor and Adele, who each walked away with three awards. Also of note — Beyoncé won favorite soul R&B female artist and Rihanna won favorite Soul R&B album, and even though both ladies weren't able to make it to the show, they made sure to thank fans in special video messages. "I am so excited by this award because it was voted on by all of my fans." "And I love you guys, thank you!"
