Selena Gomez hit the beach on Monday for the star-studded 27th birthday party of Ashley Tisdale, and had a hard time keeping her two feet on the ground.

The Monte Carlo cutie, 19, ran around in the sand, and joked around with her beau Justin Bieber's good friend Alfredo Flores, who at one point threw Gomez over his shoulder, fireman style.

Meanwhile, Gomez's Spring Breakers costar and Tisdale's best friend, Vanessa Hudgens, 23, brought her boyfriend Austin Butler to the party, and per usual, the two were quite cuddly.

As for the birthday girl...

Tisdale, donning a sexy fringed bikini top, was caught kissing and cuddling with her on-again, off-again beau, director Scott Speer .

Though Bieber wasn't able to join his girlfriend and her gal pals, he did have a good reason. The "Boyfriend" singer, 18, is a bit under the weather, and all the while trying to film the music video for his latest single "As Long As You Love Me." Bieber tweeted:

"Feeling crappy. big week coming up. #AsLongAsYouLoveMe video shoot."

Gomez, who took a break from singing to act in the fun and flirty film Spring Breakers, recently revealed she too is gearing up to get back into music.

"I have a thousand ideas," she told MTV News. "This album is going to be the first one that I'm actually going to spend as long as I want — it can be two months, it could be a whole year before this album comes out — so I'm going to have my freedom with it. It'll be, like, my tell-all, in a way."
