MANILA — Kiefer Ravena celebrated his birthday anew on October 27, but turning 31 years old just got sweeter for the Japan B.League star.

The former Gilas Pilipinas received a message from his girlfriend Diana Mackey, with the former Pinoy Big Brother: Otso housemate making their relationship official through an Instagram post.

"Happy birthday @kieferravena15, the best plot twist of my 2024," Mackey wrote for the Yokohama B-Corsairs guard.  

"Getting to know you has been the craziest, yet most exciting adventure. You are the most hard-working, passionate, and caring person I know, and you continue to amaze me every day." 

"Couldn't be prouder of you and all the amazing things you have and will accomplish. Cheers to celebrating our first of many birthdays together! Mahal kita."

"P.S. can't wait to watch you play live and be the annoying overly supportive girlfriend sitting on the bench," she added.

Mackey is the second personality that the former Ateneo de Manila University guard has been linked to since his break-up with fellow Blue Eagles star Alyssa Valdez in 2022.

It was in 2023 when the older Ravena brother shared pictures with Kholeen Ortiz, but there was no confirmation from concerned parties whether they were officially a couple. 

Also on Sunday, Ravena powered Yokohama to a 77-75 win against his former team, Shiga, while debuting a Player Exclusive (PE) of Jordan Brand's flagship sneaker, the Air Jordan XXXIX.
