Tennis superstar Caroline Wozniacki is engaged again ... to another athlete!
The former #1 player in the world said, 'Yes' to NBA star David Lee ... 8 months after going public with their relationship.
"Happiest day of my life yesterday saying yes to my soulmate," Wozniacki said ... while posting a photo of her MASSIVE engagement ring.
Wozniacki was previously engaged to golfer Rory McIlroy -- but things ended terribly in 2014 when he called things off AFTER they sent out the wedding invitations.
