Maria Sharapova keeps fans guessing with 'engagement' ring as she joins Alicia Keys and Jessica Pare at Jason Wu show

She started Mercedes-Benz Fashion Week with a bang, displaying a new sparkler on her engagement finger as she attended the Phillip Lim for Target show.
Keeping the rumours alive, Maria Sharapova sported the same glittering bling as she arrived at the Jason Wu show at 82 Mercer in New York City on Friday.
Creating a sexy school girl look, the 26-year-old tennis player - who is dating fellow tennis pro Grigor Dimitrov, 22 - was clad in a long-sleeved, black A-line frock that featured sheer, floral lace around the neckline.

Clearly also menswear-inspired, the short, pleated dress included a crisp, white collar
attached to an elongated piece of black fabric, mimicking a tie.

Breaking up the number, the German sports star cinched her waist with a black leather belt, matching her laced, peep-toe booties.
Coordinating with her sharp look, Maria opted for sleek hair, parting her locks to the side and styling them in a stick straight 'do.
Lightening up her gothic ensemble, the blonde beauty wore minimal makeup.
She played up her eyes with some mascara and liner as the rest of her face radiated with a natural dewy glow and pink lipstick.
Seeming to have a wave of sheer madness, Alicia Keys, 32, and Jessica Pare, 32, also attended the runway show, incorporating dark, see-through fabrics into their outfits.
Alicia hugged her curves with a black corset blouse, topped with a sheer, polka-dotted neckline, and teamed the pieces with a fitted navy pencil skirt and black, ankle-strap heels.

Meanwhile, Mad Men's Jessica Pare was dashing in a sleeveless, embroidered, black-and-nude dress that was spruced up with a collar and front pockets.
On her feet, she wore a pair of strappy black heels, creating a busy ensemble.
Vogue Editor Anna Wintour was also in attendance, wearing a pink tweed skirt suit to critique Jason Wu's Spring 2014 fashions.

Yet, even if the editor-at-large has one negative thought, Maria sure adored the collection.
'Lovely show by Jason Wu. What a humble guy! Loved the delicate lace details, and the finale dress. #NYFW,' she tweeted.

Maria undoubtedly sparked speculation that she and her boyfriend are getting very serious as she stepped out with a ring on Thursday.
While it didn't look like a conventional engagement ring, the bespoke design hinted that it could be a love token from someone special.
Maria and Grigor began dating last year and have been inseparable, with Maria often cheering Dimitrov on courtside.
