Paris Hilton & More Wish Britney Spears A Happy Birthday!

Singer Britney Spears celebrated another birthday on Friday and famous friends like Paris Hilton are paying tribute!

On Friday, December 2, the pop star turned 41. It's been a busy year for Britney, marrying her long-time boyfriend Sam Asghari in June and releasing her first single in six years, "Hold Me Closer" with Sir Elton John in August.

Hours before her birthday, the "Princess of Pop" shared a video on Instagram that showed her dancing around in a pink bikini. In the meantime, the Internet celebrated as Britney took another trip around the sun!

On Friday, Paris Hilton took to Twitter to wish the "Toxic" singer a happy birthday with two throwback snaps that showed them posting together when they were younger.

"Happy birthday @BritneySpears!" she tweeted. "So many magical memories with you after over two decades of friendship! Thank you for being such an incredible friend with the most beautiful soul. You deserve all the happiness in the world!"

In a two-minute video, Good Morning America took to Twitter to take a look back at Britney’s start, performing on “Star Search” and “The Mickey Mouse Club.” In an interview, Britney said she started taking her singing profession seriously when she was only 8 years old!

In the late 90s and early 2000s, her hit songs shot to the top of the charts. In 2001, Britney performed at the MTV Video Music Awards with a yellow snake around her neck and then released “Toxic” two years later.

2007 gave fans the hit song “Gimme More” before she followed it up with “Circus” a few years later. In 2011, she released her album “Femme Fatale” and released her latest album, “Glory” in 2016, which featured the hit single “Make Me.”

Consequence paid tribute to Britney by ranking her top ten hit songs. It wasn’t a surprise to see “Oops!... I Did It Again” in the number one spot. “Gimme More” was ranked second while “Toxic” was ranked third, despite being dubbed a “modern masterpiece.”

The rest of the list included “…Baby One More Time,” “I’m A Slave 4 U,” “Lucky,” “Stronger,” “Piece of Me,” “Overprotected,” and the lesser-known “Mood Ring,” which was included as a bonus cut on the Japanese edition of the 2016 studio set.

Another Britney fan shared a video featuring the young pop star and her backup dancers practicing the choreography for “…Baby One More Time.” The caption read, “mind you she was 16 here. Happy birthday to the legendary miss Britney Spears.”

Fans were quick to praise the video, with one fan writing, “She was BORN to be a pop star, but ended being THE princess of pop, and THE star of generations.” Another follower agreed, writing, “she had a choreography, and a dream, now she’s the most successful female artists of a decade! THE PRINCESS OF POP.”

Even Mr. Monopoly couldn't forget that Friday was Britney's birthday. The beloved character took to Twitter to share a link to the Britney Spears Monopoly board, which will only set fans back $44.99 (plus shipping!). Instead of houses, the board lets fans sell songs like “Toxic,” “Lucky,” and “Baby One More Time.”

With the holidays just around the corner, Britney Spears fans might want to add this one to their Christmas list!
