Caitlyn Jenner celebrated her 69th birthday in style on Sunday. Jenner spent her special day soaking up the sun in the Mexican resort of Los Cabos with her 22-year-old pal Sophia Hutchins, as per reports. The rumored couple was seen heading to sun loungers at the resort in their swimsuits and flowing colorful dusters.

The reality star, who famously transitioned from male to female in 2015, showed off her ample assets in a low-cut white one-piece with one straight shoulder strap and a diagonal strap across the chest. And since the swimwear was quite high-cut, it showcased her long legs perfectly.

Caitlyn looked radiant on her birthday as she made her way towards the loungers on the beach with her long brown hair left loose and a pair of dazzling diamond earrings. She also added a large floppy sunhat and shades and wore a green foliage-themed long duster on top of the swimsuit.

Meanwhile, Caitlyn's rumored girlfriend Sophia opted for a white bikini with a bra top and tiny bottoms. And, just like Caitlyn, Sophia too added a floral-themed duster and gold and black sunglasses, while her blonde hair was tied back.

Sophia, who claims to be a transgender like Caitlyn, met the parent of Kendall and Kylie while a student at Pepperdine University in Malibu. As per reports, she now lives with the 'I Am Cait' star and serves as the executive director of her foundation.

On the occasion of her birthday, Caitlyn was spotted reclining in the sun and topping up their tans. The couple also seemed to quite enjoy taking a stroll around the tropical grounds of their vacation getaway.

The reality TV star's birthday vacation comes after she wrote an opinion piece published in The Washington Post admitting she had made a mistake in voting for Donald Trump in the 2016 presidential election. The Olympic decathlete, who was previously married to 'Keeping Up With The Kardashians' momager Kris Jenner, slammed Trump for "relentlessly attacking" transgender people.  

"He has ignored our humanity. He has insulted our dignity. He has made trans people into political pawns as he whips up animus against us in an attempt to energize the most right-wing segment of his party," Caitlyn wrote in her opinion piece.
