Anna Kournikova has famously been cagey about her relationship status over the course of her career.
And the 34-year-old former tennis star is still not being very forthcoming, as some massive hardware appeared on her hand in a recent snap with her half brother Allan.
Her relationship with Enrique Iglesias, 40, has reportedly been on and off since they started seeing each other in 2001.
The famous tennis beauty posted three different pictures to Instagram, all showing her with her 11-year-old half brother, who is a golf prodigy and just won another competition.
In the first two posts, Anna can be seen beaming next to an equally happy Allan who's holding a large trophy.
The Russian stunner wore a black long-sleeve mini dress, but toned down the sexiness factor with a pair of black leggings and black high top sneakers.
She hid her normally flawless visage behind some large, dark aviator sunglasses and had her hair up in a simple ponytail for the celebratory occasion.
It was the final picture that depicted the often-elusive jewelry however.
As she poses with her right arm around her little sibling, some massive rings can be seen on her left ring finger.
They appear to be the same massive solitaire with baguettes and sizable diamond eternity band that have been intermittently seen on the athlete's hand in the past.
Wedding rumors have plagued the couple on and off since 2003 and in 2010 Kournikova admitted that, while she and Iglesias had been together for several years, they had no plans to marry.
The pair were dogged by split rumors in 2013, and in 2014 Enrique revealed that Anna hadn't even met his famous father Julio yet.
