Delilah Hamlin was spotted visiting a gorgeous natural swimming hole in Tulum, Mexico on Saturday, June 12, while on vacation with her longtime boyfriend, Eyal Booker.
During their tropical adventure, the 23-year-old beauty and the hunky Brit were seen diving into the water-filled sinkhole and exploring the exotic cenote.
A cenote is a natural pit resulting from the collapse of limestone bedrock that exposes groundwater. The regional term is specifically associated with the Yucatán Peninsula of Mexico, where they were commonly used for water supplies by the ancient Maya, and occasionally for sacrificial offerings.
The up-and-coming model showcased her enviable figure in a blue bikini from Emily Ratajkowski's swimswear line, Inamorata, featuring a wrap around triangle top and matching bikini bottoms. She styled the look with beaded necklaces, beaded belly chain and pigtails in her long blonde hair.
Her muscled-up 24-year-old man coordinated navy blue swim trunks.
The affectionate duo were reportedly staying at the stunning Papaya Playa Project resort, which famously boasts a traditional Mayan design.
Delilah's younger sister Amelia is no stranger to PDA packed vacations with her own boyfriend, Scott Disick. According to an OK! insider, the young women are getting competitive over their respective relationships.
"They've been competing with each other for years, and now that they both have celeb boyfriends, they're convinced the other is trying to hog the spotlight," an insider spills.
Ever since Amelia, 20, hooked up with the dad-of-three, 38, last fall, Delilah's "annoyed because her sister's getting way more attention than she is," dished the insider.
"Now, whenever Delilah packs on the PDA with Eyal, Amelia feels like she's doing it for attention," adds the insider. "If they keep trying to one-up each other, things could get pretty raunchy!"
"They push each other's buttons," the insider said of the famous sisters.
