Selena Gomez Keeps A Tight Grip (PHOTOS)

Selena Gomez is hardly ever pictured without her boo, Justin Bieber anymore. But as much as Selena likes to play with Justin, she also has to get her butt to work and no one knows this better than the 19-year-old herself, just look at how much she's accomplished at such a young age.

Selena kicked off her tour in Boca Raton, Florida on Thursday. The teen has been spotted at Universal Studios down in the sunshine state as well as at the Wizarding World of Harry Potter, but she decided to spend some down time relaxing by the pool.

Rocking a striped bikini, Selena got her tan on. Luckily she had a good grip on her bikini top as she unhooked it to avoid tan lines, as every girl knows is a key factor for proper tanning etiquette. She made sure not to let anything slip as cameras were ready to snap any move that might have went wrong.
