Selena Gomez Shares Body Positive Message Along With Video of Australian Vacation

"I chose to take care of myself because I want to, not to prove anything to anyone."

It's smooth sailing for Selena Gomez!

The "Wolves" singer kicked off this week right by joining her friends on a yacht in Sydney, Australia, wearing nothing but a teeny orange-and-black bikini, hoop earrings and a smile! 

Gomez's getaway did not include a break from social media as she shared a rather personal video to Instagram of her day on the open sea with her pals. Using a filter designed to look like old home video footage, the 25-year-old pop star filmed her friends laughing, laying out in their swimsuits and just enjoying each other's company.  

While the video was fun and lighthearted, Gomez captioned the post with a serious message about learning to love herself. 

"The beauty myth -- an obsession with physical perfection that traps modern woman in an endless cycle of hopelessness, self consciousness, and self-hatred as she tries to fulfill society’s impossible definition of flawless beauty," she wrote. "I chose to take care of myself because I want to, not to prove anything to anyone. Wind in her sails."

One person who was noticeably absent in Australia was Gomez's on-again, off-again boyfriend, Justin Bieber. 

Last week, a source told ET that Gomez is overwhelmed by the public nature of her romance with the "Sorry" singer, which might be the reason for their time apart this week. "Selena is very delicate; her 'comeback' to the spotlight has been tough -- especially with the interest in her personal life with Justin and her mother,” the source explained. “She is taking time to herself. This is not the first time she has done this."

After photos surfaced of Gomez spending time sans Bieber in Australia, a source also told ET that her closest pals are not huge fans of the 24-year-old entertainer. 

"There's a big crew of people [in Selena's circle] who really don't like Justin and they especially don't like him with Selena," the source noted. "A lot of her friends really don't like him. They think he's bad news for Selena and don't approve of the relationship."
