AceShowbiz - Singer Britney Spears has embarked on a festive journey to Mexico in honor of her 43rd birthday, celebrating not only another year but also her recent legal status as a single woman. According to sources, the global pop star "jetted off to Mexico with friends" on Monday, December 2, showcasing her love for the country with a private jet and a close circle of companions to enjoy the festivities.

"Britney treated herself to a fun vacation for her birthday. She loves Mexico and can't wait to celebrate in the sun," a source tells PEOPLE. This trip is reminiscent of her 40th birthday celebration in Cabo San Lucas with her then-fiance Sam Asghari.

Earlier in the day, the "Gimmie More" singer shared a glimpse of her pre-dinner celebrations that included "red lips and delicious wine" and a "very cute baby, baby cake" topped with strawberries. Her Instagram carousel captivated fans and highlighted her cheerful birthday spirit.

This celebration comes on the heels of a significant personal milestone. Britney's 43rd birthday marks the first day of being officially single after her separation from actor Sam Asghari. The Los Angeles court system declared the end of their marriage on May 2, following Asghari's filing in August 2023, citing irreconcilable differences. The couple originally met while filming a music video in 2016 and had their wedding in July 2022.

Despite the separation, both Spears and Asghari have expressed positive sentiments toward each other. Asghari shared his thoughts over the summer, "You learn so much from being in relationships in general. I appreciate all the amazing experiences that I got," he said, noting that Spears remains an "amazing person."

In this new chapter, Britney has embraced her newfound independence with creative expressions, including a unique video she posted in October, where she "married herself." "Bringing it back because it might seem embarrassing or stupid," she noted in her caption, "but I think it's the most brilliant thing I've ever done!"

Besides, she's rekindled her bond with her youngest son Jayden James, who reunited with her in Los Angeles, bringing a joyful dimension to her life. This has made Spears particularly happy, with sources confirming the positive impact of these familial connections.

Britney's birthday also coincides with a significant milestone in her career, the release of her sixth studio album "Circus" 16 years ago, which marked her comeback to the music scene and garnered her widespread acclaim.
