Britney Spears LOOOOVES herself some waterslides and lazy rivers ... 'cause the pop star threw on a couple of bikinis this week and hit up a Southern California waterpark -- 2 days in a row!

TMZ obtained pics of Brit -- along with her kids -- at Six Flags Hurricane Harbor in Valencia, CA on Wednesday where Ms. Spears showed off her hardbody physique in a bright pink bikini.

Brit was also spotted at the park on Tuesday ... 'cause as everyone knows, ya can't hit up all the rides in just one day!

You know how frustrating it can be when you get pen ink on your hand? Well, Amanda Seyfried got some on her forehead ... at a movie screening ... and it was pretty funny.

Seyfried was signing autographs for fans at a screening of her new movie "Lovelace" in New York City ... when she lost control of her blue sharpie, and ended up giving herself a 3rd eyebrow.

Don't worry, she still looks hot ... even after giving herself the Tobias Funke treatment.

It's a showdown of Selena Gomez' prior suitors.

Here's a topless photo that 20-year-old Nick Jonas shared on his social media page (left) -- and an equally skin-filled photo 19-year-old Justin Bieber posted on his (right).

"Gangsta" singer Kat Dahlia was busted for DUI early Tuesday morning in Miami -- and according to the police report, she cussed out the arresting officer ... and even resisted arrest.

According to the report, Dahlia was pulled over for speeding at roughly 3AM -- and when the officer approached her 2013 Nissan, a strong odor of alcohol emanated from the vehicle.

The officer claims Dahlia's speech was heavily slurred as well, so the officer asked her to exit her vehicle -- at which point, Dahlia allegedly began to grow belligerent.

The report says the officer asked Dahlia to complete a field sobriety test, and she refused, cussing at the officer instead. The report doesn't specify what cusses she used, but safe bet ... she shouldn't have used any.

Dahlia was then placed under arrest, but allegedly resisted by refusing to put her hands behind her back. The officer had to force Dahlia's hands in order to cuff her.

Dahlia was subsequently transported to a nearby police station and booked for misdemeanor DUI and resisting arrest -- but hey, at least her song's catchy.

The dreaded high-waisted bikini strikes again!!! Just days after Taylor Swift terrified the nation with some grandma's dusty old swim-diaper ... Snooki subjected her OWN DEFENSELESS CHILD to the horrific ensemble.

The pics were snapped Monday on the beach in Seaside Heights -- aka "Jersey Shore" mecca -- and luckily, Snooki's baby daddy Jionni LaValle was there to distract 11-month-old Lorenzo for long enough that he didn't go blind.

It's a battle of the beltlines!

Here's 23 year-old pop sensation and paddle board amateur Taylor Swift in the Atlantic Ocean (left) ... and 23-year-old Weiner sext-pert Sydney Leathers along the Pacific Ocean (right) -- BOTH rocking high-waisted bikinis recently.

Taylor Swift's new bikini is totes adorable according to ladies -- while in the eyes of guys ... it's the ugliest female-figure-ruining thing since your grandma hit the beach in the 1930s!

This ... means war.

Sydney Leathers is now going public with the body she once privately photographed for Anthony Weiner ... in a bikini photo shoot that begs the question: was she really worth it, Mr. Weiner?

The striped, belly button-covering bikini Taylor Swift rocked out in Rhode Island this weekend is DIVIDING THE COUNTRY ... or at least the TMZ newsroom.

Julianne Hough and "Vampire Diaries" star Nina Dobrev are two of the hottest chicks in Hollywood ... and both were at Selena Gomez's 21st bday party ... but the question is, who's hotter?

Nina Instagrammed the pic Saturday night mid-celebration of she and Hough dressed as gypsies -- per Selena's theme -- and exposing their midriffs ... making everyone with eyes super happy.

Becky Donaldson is still a bombshell!

Here's the 24-year-old "Full House" babe leaving a Beverly Hills benefit back in 1988 (left) -- and the now 49 year-old mother of two at a press gala this week (right).

Here's the 55-year-old Brooklyn based comedian Andrew Dice Clay at a L.A. movie premiere last week (left) -- and the then 41-year-old hip gyrating Elvis Presley after a concert back in 1976 (right).

Only one was ever considered a sex symbol.

The parents of Amanda Bynes believe she's a substance abuser who has become paranoid, delusional and is draining her bank account ... this according to legal docs obtained by TMZ.

Amanda's parents filed papers in an attempt to win a temporary conservatorship. In the docs, they say Amanda has become "extremely paranoid about being watched," and she covers smoke alarms with towels and tapes windows shut to prevent cameras from shooting her.

The parents go on -- Amanda has "profound issues with her body image" and is "obsessed with the fact that she (and others) are ugly."

The parents say Amanda had $4 million in the bank, but is blowing a huge amount of cash -- she spent $1.2 mil in a very short amount of time. Amanda withdrew $100k on June 4 and another $100k on July 2 and the parents have no idea where the money went, but they mention they believe she spends "a substantial amount" for marijuana and other illegal substances.

The parents say Amanda doesn't connect with reality, telling them she "cabbed it" from New York to L.A. The parents believe she's homeless.

The documents described what TMZ first reported ... that the parents are hanging their hats on the driveway fire incident to show Amanda is a danger to herself and others.

The court denied the petition for a temporary conservatorship Friday morning, because the judge wanted more info.

It was only a matter of time -- Miley Cyrus went FULL NAKED for an artsy photo shoot ... but sorry pervs, it ain't exactly a Penthouse spread.

20-year-old Miley stripped down to her birthday suit for a Marc Jacobs t-shirt -- which is part of the designer's "Protect the Skin You're In" campaign to raise awareness for melanoma research.

Of course, the slogan is carefully placed over Miley's chest to cover her nipples ... and she uses her hand to hide her hooha. You can breathe easy, Billy Ray ...

Miley posted the image on her Twitter page -- along with the caption, "Ts are available at 9 Marc Jacobs boutiques including SanFran, LA, Chicago, New York, Boston, & Savannah GA!"

Kevin Arnold would LOSE HIS MIND RIGHT NOW.

Former "Wonder Years" star Danica McKellar flaunted her figure in a punk-rock-meets-Hollywood-streetwalker outfit yesterday ... and damn, she looks GOOOD.

McKellar -- who's 38 years old BTW -- rocked the look for a new Avril Lavigne music video.

Avril was there too, but who cares.
