With her multiple tattoos proudly on display, the blond beauty can be seen posing in front of a beachfront seascape while sporting a golden, two-piece bathing suit. She captioned the snap: “Thank you for a great tour South America! I love it here! And I love you all xo❤"

Avril's beauty, however, is more than skin deep. After hearing news that her ex-husband, Deryck Whibley, was undergoing treatment for alcoholism, the 29-year-old chanteuse offered her love and support via Twitter, writing: “Hope you get well soon! #StayStrongDeryck."

Although Avril is now married to Nickelback frontman Chad Kroeger, it is clear that she still supports the man to whom she was married for four years. She added: “Spoke to @Sum41 Deryck today. I am so proud of him. He is family to me and always will be. #StayStrongDeryck”

Her rock-singer ex had shocked fans by posting photos of himself in the hospital after he collapsed due to an alcohol-related illness.

“I was stuck with needles and IV’s all over. I was completely sedated the FIRST WEEK,” Deryck wrote in a blog post titled 'Rock Bottom.' “When I finally woke up the next day I had no idea where I was. My mum and step dad were standing over me. I was so freaked out. My liver and kidney’s collapsed on me. Needless to say it scared me straight.”
