Serena Williams has been romantically linked with rapper Drakehandout

Serena Williams may have been romantically-linked to rapper Drake in recent weeks but the tennis star has now revealed that her heart already belongs to another. Talking to social media on 9 September, the 33-year-old sportswoman paid a touching tribute to the real love of her life- her sister Venus.

Alongside a collage of the pair at different stages of their careers, she wrote: "She has my heart. ❤️ Memories make my heart fill with more joy than I can express. A lifetime with @venuswilliams will not be enough."

It is not surprising that Williams and her 35-year-old sister share a close bond having been raised on tennis as siblings growing up in Compton, California. And over the past 17 years they have battled it out on the court, as both rivals and partners.

The post may have also been a thinly-veiled attempt to distract attention from her budding romance with Drake. Just days earlier the pair was caught on camera kissing in public after what appeared to be another date night.

The footage, which was uploaded on Instagram by a Drake fan account, @ovodrakevideos, shows the Young Money rapper kissing the tennis star outside a building before seeing her to her SUV. The caption read: "All the #Aubrih ship be like....Serena and Drake kissing, I don't know when this was or where it was but the fact they're kissing has me like"

It emerged after the Grand Slam star and hip hop star, 28, were snapped piling on the PDA during a romantic dinner date in Cincinnati on 23 August after weeks of speculation about their relationship.

But despite reports that the Drake is besotted with the athlete, television host Wendy Williams recently cautioned the sports star, citing the YOLO hitmaker's "player" status. "I'm worried Serena is choosing the wrong guy. Drake is younger than she is [he's 28] and a bit of a ladies' man," she said in her September contribution to Life & Style, via Classicalite. "If I were her, I'd consider Drake a snack instead of the main course. Move on before you get hurt, girl!"
