Selena, who turned 22 on Tuesday 22 July, was joined by family and friends as she toasted to another year.
Despite getting lots of presents and partying with friends, it seems Selena's lavish cake was the best gift of all.
Posting a photo on Instagram, she wrote yesterday (23 July): "@simplychocolatecph for my cake. DUDE, the most incredible chocolate. Ever. And I like chocolate."
The cake was adorned with letters, which read: 'Happy 22nd Birthday Selena'. It was also accessorised with white roses, as well as red and white berries.
She's clearly a fan!
Spring Breakers actress Selena has spent most of her birthday hanging out with model and new BFF Cara Delevingne on a yacht in the French Riviera - lucky for some!
The duo have been soaking up the sun and going on a number of adventurous excursions including a high-flying parasailing ride and jet skiing on the Mediterranean waters.
In another photo posted to Instagram, Selena looked gorgeous and sun-kissed in a silk blue outfit as she posed with her girls. She said: "Thank you SO much for my birthday wishes ☺️ -this has been the BEST birthday yet! THANK YOU!!!!"
It seems like this will be a birthday week to remember!
