Avril Lavigne slipped into a gold-colored bikini for some fun in the sun with friends in Cancun, Mexico, on Sunday. The singer flaunted her figure while relaxing on the beach, then took to the water for a bit of swimming before retreating to a lounge chair. Avril, who is currently in the middle of her South American tour, was spotted sans wedding ring during the beach day, leading some to believe that there could be trouble in paradise for her and husband Chad Kroeger — Avril and the Nickelback frontman tied the knot in the South of France back in July 2013. Though the status of Avril's marriage has yet to be commented on, it's the recent music video for her song "Hello Kitty" that has people talking. The candy-colored clip sparked lots of controversy for its use of Asian stereotypes, but Avril defended her decision, saying, ""RACIST??? LOLOLOL!!! I love Japanese culture."
