Happy birthday anniversary, Mariah Carey!

The pop icon celebrated her 47th birthday in Cabo San Lucas on Monday alongside her friends, family and boyfriend, Bryan Tanaka. Only in Mariah's World, she doesn't have birthdays -- she has epic anniversaries. Case in point: A half-naked Tanaka popping out of a giant cake during last year's festivities.

This year, Carey took a more relaxing route by renting out a private villa in the tropics to celebrate with her nearest and dearest, including her 5-year-old twins, Moroccan and Monroe.

In a snap posted to Instagram, the singer -- clad in a form-fitting gold sequined dress and sunglasses -- coyly posed behind a pile of gifts and a giant red bow. "Let the anniversary festivities begin," she wrote.

Tanaka posted more pics of the tropical getaway, including a photo of the pair relaxing oceanside with the caption, "Starting the anniversary festivities in a relaxing chic environment. #HappyAnniversary."

Though Mimi recently said she prefers to remain mum when it comes to her love life and relationship with the backup dancer, a source tells ET, "They're very much still together and happy."

The "I Don't" crooner later took to Twitter to thank her fans (and Ellen DeGeneres!) for their outpouring of "anniversary" love, tweeting, "Really moved by all your beautiful #anniversary messages. Thank you my #lambily ILYM!!"
